study of the effect of college student employment on academic performance, the following summary statistics for GPA were reported for a sample of students who worked and for a sample of students who did not work. The samples were selected at random from working and nonworking students at a university. (Use a statistical computer package to calculate the P-value. Use μ_employed − μ_not _employed. Round your test statistic to two decimal places, your df down to the nearest whole number, and your P-value to three decimal places.)

The student academic group on a college campus claims that freshman students study at least 2.5 hours per day, on average. One Introduction to Statistics class was skeptical. The class took a random sample of 30 freshman students and found a mean study time of 137 minutes with a standard deviation of 45 minutes. At α = 0.01 level, is the student academic group’s claim correct? Calculate the p-value.

An article appeared in an Australian newspaper. It described a study of academic performance and attention span and reported that the mean time to distraction for teenage boys working on an independent task was 5 minutes. Although the sample size was not given in the article, suppose that this mean was based on a random sample of 50 teenage Australian boys and that the sample standard deviation was 1.5 minutes. Is there convincing evidence that the average attention span for...

A study was designed to measure the effect of home environments on academic achievement of 12 year old students.

The final grades for 60 students were measured. Is this example an independent paired t-test or a dependent paired...
