WebFor example, assume that one were to test 1,000 null hypotheses, all of which are true, and (as is conventional in single hypothesis testing) to reject null hypotheses with a significance level of 0.05; due to random chance, one would expect 5% of the results to appear significant ( P < 0.05), yielding 50 false positives (rejections of the null … WebSolve. Example 1 • Example 2. The first step in hypothesis testing is to calculate the test statistic. The formula for the test statistic depends on whether the population standard deviation (σ) is known or unknown. If σ is known, our hypothesis test is known as a z test and we use the z distribution. If σ is unknown, our hypothesis test ... WebFor a left-tailed test, the critical value of z so that a hypothesis test would reject the null hypothesis at 10% significance level would be __________.
