Hypothesis testing: A student group claims that first-year students at a university must study 2.25 hours per night during the school week. A skeptic suspects that they study less than that on average. A class survey finds the study time claimed by 259 students is 147 minutes.

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. If α = 0.01 (or 99% confidence level), is the student academic group’s claim correct?

A professor in the education department believes that a sample of students study less hours per week when compared to the general population of university students. The general population of university students studies an average of 15 hours a week with a standard deviation of 2. The professor randomly samples 16 students and discovers her sample has a mean of 12. Use an alpha level of 0.05 to determine whether these students study less hours per week when compared to...

A class survey in a large class for first-year college students asked, "About how many hours do you study during a typical week?" The mean response of the 493 students was x = 15.3 hours. Suppose that we know that the study time follows a Normal distribution with standard deviation σ = 8.5 hours in the population of all first-year students at this university. Regard these students as an SRS from the population of all first-year students at this university....
