In order to compare the durability of four different brands of golf balls (ALPHA, BEST, CENTURY, and DIVOT), the National Golf Association randomly selects balls of each brand and places each ball into a machine that exerts the force produced by a 250-yard drive. The number of simulated drives needed to crack or chip each ball is recorded. Use a significance level of 0.05 to conduct all hypothesis tests and construct confidence intervals.

For a one-tailed (upper tail) hypothesis test with a sample size of 26 and a .01 level of significance, the critical value of the test statistic t is
For a lower tail hypothesis test with a sample size of 13 and a .10 level of significance, the critical value of the test statistic t is
A researcher looks at the mean salaries of male and female electricians and decides based on the evidence that there is no difference between the two groups. Given that there was a failure to reject the null hypothesis, it is possible that a type II error was made. Given the type of error made in this situation, what could researchers do to reduce the risk of this error? Choose a .01 significance level, instead of a .05 significance level. Increase the sample size.
In a random sample of 800 adult Americans, 605 of them were nonsmokers. The following question was asked: Should the federal tax on cigarettes be raised to pay for health care reform? In this sample 351 nonsmokers and 41 smokers answered "yes." Let p1 and p2 be the proportions of nonsmokers and smokers, respectively, in the general population of adult Americans who would answer "yes" to the question. Use a significance level of 0.01 and an appropriate confidence interval to test the claim that there is no difference in the opinion of the two groups.
In attempting to improve student services, a college investigates its registration process and finds that for 12 randomly selected students, the mean registration time was 73.2 minutes with a standard deviation of 14.2 minutes. Another college finds that for 15 randomly selected students, the mean registration time was 42.3 minutes with a standard deviation of 9.8 minutes. At the 0.01 significance level, test the claim that the two samples came from populations with the same means. Assume equal population variances.
For a statistics class project, a college student randomly samples 75 men who exercise at a gym regularly and 68 women who exercise at a gym regularly. The college student records the number of minutes each person exercises in a given week. The college student believes that the mean number of minutes per week is lower for men than for women. The college student conducts a hypothesis test at the 5% significance level. What conclusion can you draw from the output? The data provide sufficient evidence to reject the null hypothesis and to conclude that the mean number of minutes exercised per week is lower for men than for women. The data provide sufficient evidence to conclude that there is no difference in the mean number of minutes exercised per week for men and women. The data do not provide sufficient evidence to conclude that the mean number of minutes exercised per week is lower for men than for women. We accept the null hypothesis, and conclude that there is a difference in…
For Business versus Engineering majors conduct a full, two-sample hypothesis test at the 10% significance level (assume the variances are not equal). Claim: the average ’30-Year ROI’ for Business majors is less than for Engineering Majors. Use all the steps of hypothesis tests.
An information technology help desk has a service level agreement (SLA) that says that clients should be contacted about their service requests within 1 hour (60 minutes) of the help desk receiving the request. Jackie, the help desk manager, wants to check if the help desk is actually taking longer than 60 minutes to respond. For a random sample of 20 service requests, Jackie obtained the time between the help desk receiving the request and the client being contacted. The marketer conducts a one-mean hypothesis at the 5% significance level, to test whether the response time is greater than 60 minutes. (a) Which answer choice shows the correct null and alternative hypotheses for this test? Select the correct answer below: H0:μ=20; Ha:μ<20, which is a left-tailed test. H0:μ=60; Ha:μ<60, which is a left-tailed test. H0:μ=20; Ha:μ>20, which is a right-tailed test. H0:μ=60; Ha:μ>60, which is a right-tailed test.
(a) A developer believes that the standard deviation of the house price is greater than RM230,000. At 5% significance level, is there enough evidence to support the developer's claim? b) Test at 99% confidence level that the variances of the house price is different between State A and State B, and interpret your finding.
In a study of 822 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed. Part 1 Which of the following is the hypothesis test to be conducted?
According to the U.S. Transportation Security Administration (TSA), 2% of the 771,556,886 travelers who utilized 440 federalized airports in 2017 waited more than 20 minutes in the TSA security line. The File TSAWaitTimes contains waiting Times in TSA security lines at a major U.S. airport for a recent random sample 10,531 travelers. Use these Data to test the hypothesis that the proportion of travelers waiting more than 20 minutes in TSA security lines at this airport is the same as the national proportion at α = .05 Data given: Time In Line Mean 11.99496 Median 11.97536 Standard Deviation 3.992043 Confidence Level(95.0%) 0.076253 Provide a 95% confidence interval with interpretation
