WebThe result that H0is not rejected is a weak statement that should be interpreted to mean that H0is consistent with the data. Thus, in any procedure for testing a given null hypothesis, two different types of errors can result. The first, called a type I error, is said to result if the test rejects H0when H0is true. Web27 nov. 2013 · a small p-value means: assuming H0 is true, it is extremely hard to obtain the observed result from our sample, which means: 1) Null hypothesis H0 is false OR 2) Our sample was not drawn from null population. Either way, we reject H0. And we quantify ‘small’ with confidence level. That's why when p < alpha, we reject H0.

WebTrue or false: a) If we reject H0, then we conclude that H0 is false. b) If we do not reject H0, then we conclude that H0 is true. c) If we reject H0, then we conclude that H1 is true. d) If we do not reject H0, then we conclude that H1 is false. Question True or false: a) If we reject H 0, then we conclude that H 0 is false. Web8 sep. 2008 · Null hypothesis are never accepted. We either reject them or fail to reject them. The distinction between “acceptance” and “failure to reject” is best understood in terms of confidence intervals.

WebIf we choose a low p, say 0.25, there's going to be a higher chance of accepting our Ha even if Ho was true (Type I error). Imagine if the true p was 0.4, making our Ho true and Ha false. If we take a sample and get something like p^ = 0.55, with an assumption of p = 0.25 that might still have a p-value below alpha, making us accept Ha even though it was false. bodybuilding hd imagesWebWe reject the null hypothesis, because the evidence we've observed and the predictions made by the hypothesis do not match very well.
