According to a national survey, the average American drinks 3.1 cups of coffee per day. A university believes its students drink more. A random sample of 50 students shows mean of 3.4 cups per day with a standard deviation of 0.8 cups. At the 0.02 significance level, test the claim that students at this university drink more coffee than the national average. Clearly state the hypotheses and show all steps.

A researcher wants to compare the average number of hours students living in dorms exercise per week to those living off-campus. A random sample of 12 students living in dorms and 14 students living off-campus was taken. The results (in hours per week) are as follows:Dorm Students: 3.5, 4.0, 3.8, 2.9, 3.6, 4.2, 3.7, 3.1, 3.9, 4.1, 3.0, 3.4Off-Campus Students: 2.5, 3.0, 2.8, 3.1, 2.7, 2.9, 2.6, 3.2, 3.0, 2.4, 2.7, 2.5, 2.8, 2.9Using a 0.1 level of significance, test whether there is a significant difference in the average weekly exercise time between students living in dorms and those living off-campus. Clearly define the hypotheses, show all calculations, and state your conclusion.

The administration wants to know if the mean time students spend on TikTok per day exceeds 2 hours. In a survey of 40 students, the mean was 2.3 hours with a standard deviation of 1.1 hours.Perform a hypothesis test at the 0.01 significance level. Is there enough evidence to support the claim that students spend more than 2 hours per day on TikTok?

A tire manufacturer claims that the standard deviation of the air pressure in its tires is no more than 1.5 PSI. To test this claim, a quality inspector randomly selects a sample of 10 tires and measures the pressure in each one. The sample has a standard deviation of 2.2 PSI. Assume the air pressures are normally distributed. Use a 0.05 significance level to test the manufacturer’s claim.
