The average American consumes 94 liters of alcohol per year. Does the average college student consume more alcohol per year? A researcher surveyed 13 randomly selected college students and found that they averaged 95.6 liters of alcohol consumed per year with a standard deviation of 15 liters. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: ? Select an answer H1: Select an answer c. The test statistic [? (please show your answer to 3 decimal places.) %3D d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is (? f. Based on this, we should | Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest that the population mean amount of alcohol consumed by college students is not significantly more than 94 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 94 liters per year. The data suggest the populaton mean is significantly more than 94 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 94 liters per year. The data suggest the population mean is not significantly more than 94 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 94 liters per year.
