answer nine questions using appropriate statistical inference procedures. Use Minitab for all statistical procedures. Do not do any statistical calculations or draw graphs by hand. Part 1: For each of the questions, you will be asked to: • identify the response (and explanatory) variable and the type(s) • state your null and alternative hypotheses • explain why the conditions for the inference are met • provide the results of the appropriate significance tests in Minitab • provide a brief conclusion based on the p-value of the inference Part 2: Make conclusions about your entire analysis: Explain if the results of your hypothesis tests show that students’ social activities help or hinder their education at PSU. What recommendations can you make to the Department of Statistics to report to President Graham Spanier for improving the social and educational habits of students at PSU? Alcohol and Drug Use 1: Is the true population mean age of first alcoholic drink for PSU Stat 200 students less than 21? 2: Do a majority of PSU Stat 200 students think marijuana should be legalized? 3: Is there a difference in the true population mean ages of first marijuana smoke and first alcoholic drink for PSU Stat 200 students? 4: Is the true population mean GPA higher for PSU Stat 200 students who have not driven drunk compared to those who have? 5: Is there a difference in the true population proportion of PSU Stat 200 students who have cheated on an exam based on whether or not they have driven drunk? 6: Is there a relationship between preference of seat location in class and their alcoholic beverage of choice for PSU Stat 200 students? 7: Is there a linear relationship between GPA and the age of first alcoholic drink for PSU Stat 200 students? 8: Is there a difference in the true population mean GPA of PSU Stat 200 students based on how many drinks they have in one sitting? 9: Is there a difference in the true population median GPA of PSU Stat 200 students based on their favorite drug?
