- Women executives A company is criticized because only13 of 43 people in executive-level positions are women.The company explains that although this proportion islower than it might wish, it’s not surprising given thatonly 40% of all its employees are women. What do you think? Test an appropriate hypothesis and state your con-clusion. Be sure the appropriate assumptions and condi-tions are satisfied before you proceed.Identify the type I error and the type II error that correspond to the given hypothesis. The percentage of high school students who graduate is equal to 55 %. Identify the type I error. Choose the correct answer below. A. Fail to reject the null hypothesis that the percentage of high school students who graduate is equal to 55 % when that percentage is actually different from 55 %. B. Reject the null hypothesis that the percentage of high school students who graduate is equal to 55 % when that percentage is actually equal to 55 %. C. Fail to reject the null hypothesis that the percentage of high school students who graduate is equal to 55 % when the percentage is actually equal to 55 %. D.

- Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. The principal of a middle school claims that test scores of the seventh-graders at his school vary less than the test scores of the seventh-graders at a neighboring school, which have variation described by σ= 14.7. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms. a) There is not sufficient evidence to support the claim that the standard deviation is greater than 14.7 b) There is sufficient evidence to support the claim that the standard deviation is less than 14.7 c) There is sufficient evidence to support the claim that the standard deviation is greater than 14.7 d) There is not sufficient evidence to support the claim that the standard deviation is less than 14.7The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: Notice that the alternative hypothesis is a two-tailed test.
