WebMar 9, 2024 · A null hypothesis is a theory based on insufficient evidence that requires further testing to prove whether the observed data is true or false. For example, a null hypothesis statement can be “the rate of plant growth is not affected by sunlight.”. It can be tested by measuring the growth of plants in the presence of sunlight and comparing ... WebSince ZsTAT falls into the nonrejection region, do not reject Ho. O D. Since ZSTAT falls into the rejection region, do not reject Ho. If you use a 0.10 level of significance in a (two-tail) hypothesis test, the decision rule for rejecting Ho:H=11.7, if you use the Z test, is shown below. Reject H, if ZSTAT< - 1.645 or ZSTAT> + 1.645.

WebFeb 26, 2010 · The Power of the Test. Rejecting a null hypothesis when it is false is what every good hypothesis test should do. Having a high value for 1 -b (near 1.0) means it is a good test, and having a low value (near 0.0) means it is a bad test. Hence, 1 -b is a measure of how good a test is, and it is known as the “power of the test.”. WebAnswer to Solved The probability of rejecting HO when HO is true is. This problem has been solved!

WebHere, Ho and Ha are complementary; p is always going to be in one or the other. But now, we want to actually do the test. What sampling distribution do we use, if Ho is an inequality? Well, we can choose from any p that is <= 0.5. If 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 ... WebMar 3, 2024 · They key thing to remember is that p-values are a conditional probability. P-value calculations assume that the null hypothesis is true. So, a p-value of 0.01 indicates that there is a 1% probability of observing your sample results, or more extreme, *IF* the null hypothesis is true. The kicker is that we don’t whether the null is true or not.
