The average American consumes 89 liters of alcohol per year. Does the average college student consume less alcohol per year? A researcher surveyed 15 randomly selected college students and found that they averaged 87.3 liters of alcohol consumed per year with a standard deviation of 15 liters. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer v H1: ? v Select an answer v c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer g. Thus, the final conclusion is that ... the null hypothesis. O The data suggest the population mean is not significantly less than 89 at a = 0.05, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is equal to 89 liters per year. O The data suggest that the population mean amount of alcohol consumed by college students is not significantly less than 89 liters per year at a = 0.05, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is less than 89 liters per year. O The data suggest the populaton mean is significantly less than 89 at a = 0.05, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is less than 89 liters per year.
