The Dean of Instruction at a local college requested that a new standardized test for an introductory statistics course be developed with the requirement that it should have µ = 120 points and σ = 15. A class of 30 students complete the new test with a mean grade of 115. Conduct a hypothesis test at α = .05 to determine whether the claim that µ = 120 can be supported. Use the p-value approach and complete the following to...

Are college students who take a freshman orientation course more likely to stay in college than those who do not take such a course? An article reported that out of 100 randomly selected college students who participated in an orientation course 57 returned for a second year. Of the 95 randomly selected students who did not take the orientation course, 40 returned for a second year. Test the claim that a larger proportion of college students return for a second...

This Question: pts Question Help In a previous year, 01% of females aged 15 years of age and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 300 females aged 15 years of age and older and finds that 195 are living alone. Is there sufficient evidence at the 0.01 level of significance to conclude the proportion has changed? Identify the null and alternative hypotheses for this test. O A. Ho...

(Refer to HW6 #6) According to a survey, 73 males out of 786 and 43 females out of 943 report that they usually drive 10 or more miles per hour over the speed limit in Kansas City. We are interested in comparing the proportion of male speeders with the proportion of the female speeders. Is the proportion of male speeders higher than the proportion of female speeders? Perform a hypothesis testing at 6% significance level by answering the following questions....

A researcher is interested in determining whether there is a difference in male college students and female college students' preference for taking online classes over on-campus classes. The researcher surveys 82 female students, and found that 15 preferred online classes. The researcher surveys 70 male students, and found that 10 preferred online classes. Let's perform a hypothesis test at the 5% significance level. Test whether the proportion of females who prefer online classes is greater than the proportion of males...
