The average American consumes 82 liters of alcohol per year. Does the average college student consume more alcohol per year? A researcher surveyed 12 randomly selected college students and found that they averaged 103 liters of alcohol consumed per year with a standard deviation of 25 liters. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use z-test for a population proportion b. The null and alternative hypotheses would be: Ho: ?# H1: ?~ > c. The test statistic ? d. The p-value = e. The p-value is ? a = f. Based on this, we should (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population mean is not significantly more than 82 at a = 0.01, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is equal to 82 liters per year. O The data suggest the populaton mean is significantly more than 82 at a = 0.01, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is more than 82 liters per year. The data suggest that the population mean amount of alcohol consumed by college students is not significantly more than 82 liters per year at a = 0.01, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is more than 82 liters per year.
