	Alternate hypothesis - Wikipedia, the free encyclopedia
		The alternate hypothesis, or alternative hypothesis, together with the null hypothesis are the two rival hypotheses whose likelihoods are compared by a statistical hypothesis test.
		Usually the alternate hypothesis is the possibility that an observed effect is genuine and the null hypothesis is the rival possibility that it has resulted from random chance.
		Incorrectly rejecting the null hypothesis is a Type I error; incorrectly failing to reject it is a Type II error.

		The null hypothesis is that the incoming aircraft is not hostile.
		The alternate hypothesis is that the incoming aircraft is hostile.
		If the alternate hypothesis is false and actually the incoming aircraft is a commercial airliner carrying hundreds of civilian passengers, the consequence of committing a Type I error is killing hundreds of innocent people and even starting a war that may eventually cause more deaths.

		If we find that the data suggest the null hypothesis cannot be rejected, and no difference is present in the maximum wall thickness, we must conclude that the alternate hypothesis and our hypothesis of interest are probably false.
		The rules of hypothesis testing state that it is important to specify the probability at which you, the researcher, will reject the null hypothesis of no difference.
		We may reject the null hypothesis when it is indeed true (thereby making a Type I or alpha [a] error), or we may accept the null hypothesis when it is indeed false (a Type II or beta [b] error).

	Statistical Hypothesis Testing
		Hypothesis testing often confuses people but it is the keystone of most statistical applications.
		The alternate hypothesis is that the process change or treatment has an effect, or something is wrong with the process.
		It is the integral of the distribution from 0 to 12.59, and 95 percent of the area under the curve is to the left of 12.59.

		The blue area is β, the probability of failing to reject the null given that the alternate hypothesis is true.
		One problem with the use of null hypothesis significance testing is the tendency for those failing to reject the null to instead accept the null, whether overtly or covertly.
		Their intent is generally to say that the state of affairs is closer to the null hypothesis than to the alternate, despite being able to "legally" accept the null, rather than passively failing to reject it.

	Hypothesis Testing
		Hypothesis testing is the process of determining whether a confidence interval includes a previously known population mean value.
		The alternate hypothesis is the supposition that there is a change in the value from some pre-existing, historical, or expected value.
		Although we run around saying we failed to reject the null hypothesis, in practice it means we left the null hypothesis standing: we de facto accepted the null hypothesis.

		The alternate hypothesis is the statement that we suspect is true.
		The alternate hypothesis is constructed in such a way that it is the one to be accepted when the null hypothesis must be rejected.
		The alternate hypothesis, then, will be a statement that the population mean is either less than, greater than, or not equal to the value k.

	Hypothesis testing
		In a hypothesis test, you have two hypotheses: One is called the null hypothesis, and the other is called the alternate hypothesis.
		So the null hypothesis is that he hits the bullseye 98% of the time, and the alternate would be that he hits the bullseye less than 98% of the time.
		However, if you were doing this hypothesis test because you had hundreds of employees who were complaining of allergies, you might choose a higher level of significance (probably 0.05), since, if you are going to make an error, you would rather error on the side of protecting your employees.

	Hypothesis Testing
		Hypothesis testing is one of the most important tools of application of statistics to real life problems.
		Always the null hypothesis is tested, i.e., we want to either accept or reject the null hypothesis because we have information only for the null hypothesis.
		Although hypothesis tests are a very useful tool in general, they are sometimes not appropriate in the environmental field.

		This Alternate Hypothesis distribution refers to a different hypothetical population where the sample mean differences average out to +10.
		This means that if the Alternative Hypothesis is true and there is actually a difference of ten points we won't detect it for that part of the sampling distribution (the part to the left of the line).
		If the Alternate Hypothesis is true and the actual population mean is 10, we will detect the difference for the part of the sampling distribution to thr right of the line at 9.8.

	HYPOTHESIS TESTING (Site not responding. Last check: 2007-10-13)
		A statistical hypothesis is a claim or a statement about the value of a single parameter or about the values of several parameters.
		A statistical test of hypothesis is a method for deciding which of the two hypotheses is correct and is based on the method of proof by contradiction.
		In hypothesis testing, this error is the same as rejecting the null hypothesis when it is true.

		The alternate hypothesis would be stated, "Persons treated with lovastatin have different (higher or lower) cholesterol levels than persons not treated with lovastatin.
		This alternate hypothesis is stated as a 2-tailed hypothesis, which considers it possible that lovastatin has the opposite effect of that anticipated by the researchers.
		Hypothesis testing allows a researcher to decide whether a difference between numbers is more likely due to random variation (1) or a true difference (2).

	_U.B.C. BIOLOGY 300
		For the purpose of statistical testing of a hypothesis it is normal to formulate a pair of hypotheses: the null hypothesis (Ho) and the alternate hypothesis (Ha).
		The alternate hypothesis, it’s opposite counterpart, is usually the idea that we would like to prove (but can’t because proof is impossible).
		The degrees of freedom for a hypothesis test are used to determine the shape of the theoretical distribution, since many distributions (like normal, binomial, Poisson and others) can take on different shapes as their parameters change.

	Hypothesis Testing
		Hypothesis testing refers to the process of using statistical analysis to determine if the observed differences between two or more samples are due to random chance (as stated in the null hypothesis) or to true differences in the samples (as stated in the alternate hypothesis).
		The alternate hypothesis (Ha) is a statement that the observed difference or relationship between two populations is real and not the result of chance or an error in sampling.
		Hypothesis testing is the process of using a variety of statistical tools to analyze data and, ultimately, to fail to reject or reject the null hypothesis.

		Once you have rejected the null hypothesis, you are allowed to entertain (though have not proven) an alternate hypothesis that would better explain the numbers you saw.
		Secondly, this test does not measure the plausibility of your alternate hypothesis generating this data, it only indicates there is “room” to entertain alternatives.
		And no, you cannot use the chi square to prove your alternate hypothesis because that is saying that something other than chance is responsible, and we’d be changing the null hypothesis.

		A null hypothesis EMBED Equation is a statistical hypothesis that contains a statement of equality, such as EMBED Equation “H subzero” or “H naught” The alternate hypothesis EMBED Equation is the complement of the null hypothesis.
		The only way to be certain the null hypothesis is true or false is to test the entire population; this is not always convenient.

		In the case of the circuit boards at Sikasso, the hypothesis would be: “exactly 20% of the defects on the circuit board are traceable to the CPU socket”.
		If the hypothesis is not rejected, 20% of the defects will actually be traced to the CPU socket but if enough evidence is statistically provided that the null hypothesis is untrue, an alternate hypothesis should be assumed to be true.
		Suppose that in case of the defects on the circuit boards, a sample of 40 boards was randomly taken for analysis and 45% of the defects were actually found to be traceable to the CPU sockets.

	The Alternate Hypothesis
		One of the strange things about statistical hypothesis testing is that we have no viable means of “proving” that the so-called alternate hypothesis is true.
		Typically this is the hypothesis we hope to confirm because our main interest is to discover relationships and connections that explain the way the world works.
		Upon rejecting the Null hypothesis, we conclude that there are solid statistical grounds for accepting the Alternative as a sound version of reality—at least in the sample under test.
