1) a) Choose one of the following quantitative variables from the data set: Age, Weight, Cell Phone, Study, TV, Sleep, Pets, or Work.
b) Find a 95% confidence interval for the population mean [variable] of all ABC students.
c) Find a 95% confidence interval for the population mean [variable] of all female ABC students.
d) Find a 95% confidence interval for the population mean [variable] of all male ABC students.
e) Interpret each interval and compare the intervals.
2) a) Find a 99% confidence interval for the population mean age for all ABC students' fathers.
b) Find a 99% confidence interval for the population mean age for all ABC students' mothers.
c) Interpret each interval and compare intervals.
3) Find a 95% confidence interval for the population mean GPA score for all ABC students. Interpret your results.
4) Test the hypothesis that the population GPA of all students in MTH-107 is not equal to 2.95. (Note: Choose a level of significance α = 0.1, 0.05, 0.01)
5) Test the hypothesis that the population mean age of all students in MTH-107 is less than 26 years old. (Note: Choose a level of significance α = 0.1, 0.05, 0.01)
6) Choose one of the following (Note: α = 0.05):
a) Test the hypothesis that the population mean weight of all ABC students is less than 165 pounds.
b) Test the hypothesis that the population mean amount of time all ABC students study per day is less than 3.5 hours.
c) Test the hypothesis that the population mean amount of time all ABC students spending sleeping is less than 7.5 hours per day.
