Test the claim that the mean GPA of night students is significantly different than 2.5 at the 0.05 significance level. The null and alternative hypothesis would be: Но :р 2.5 Но: и — 2.5 Но:р > 0.625 Но: 0.625 Hi:д 2.5 Hi:р + 0.625 The test is: two-tailed left-tailed right-tailed o Based on a sample of 20 people, the sample mean GPA was 2.52 with a standard deviation of 0.07 The p-value is: (to 4 decimals) Based on this we: o Fail to reject the null hypothesis O Reject the null hypothesis
A new drug to treat a certain condition is being tested. The null hypothesis of the test is that the drug is not effective. For the researchers, the more consequential error would be for the drug to be effective, but the test does not detect the effect. Which of the following should the researchers do to avoid the more consequential error? Increase the significance level to increase the probability of Type II error. A Increase the significance level to decrease the probability of Type II error. B Decrease the significance level to increase the probability of Type II error. C Decrease the significance level to decrease the probability of Type II error. D Decrease the significance level to decrease the standard error.

Suppose the null hypothesis, Ho, is: the mean age of the horses on a ranch is 6 years. What is the Type lI error in this scenario? Select the correct answer below: O O O O You think the mean age of the horses on a ranch is 6 years when, in fact, it is. You think the mean age of the horses on a ranch is 6 years when, in fact, it is not. You think the mean age of the horses is not 6 years when, in fact, it is. You think the mean age of the horses is not 6 years when, in fact, it is not.
B. Identify the test statistic. z=___ C. Identify the P-value. P-value=___ D. What is the conclusion based on the hypothesis test? The P-value is (greater than/ less than) the significance level of α=0.05, so (reject/ fail to reject) the null hypothesis. There (suffiecient/ is not sufficient) evidence to warrant rejection of the claim that women and men have equal success in challenging calls. Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is___<(p1-p2)<____. E. What is the conclusion based on the confidence interval? Because the confidence interval limits (include/ do not include) 0, there (does/ does not) appear to be a significant difference between the two proportions. There (is sufficient/ is not sufficient) evidence to warrant rejection of the claim that men and women have equal success in challenging calls. F. Based on the results, does it appear that men and women may have equal success in challenging…
