hypothesis problem is the topic

The average American consumes 99 liters of alcohol per year. Does the average college student consume less alcohol per year? A researcher surveyed 14 randomly selected college students and found that they averaged 94.9 liters of alcohol consumed per year with a standard deviation of 25 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 ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the populaton mean is significantly less than 99 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 99 liters per year. O The data suggest the population mean is not significantly less than 99 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 99 liters per year. The data suggest that the population mean amount of alcohol consumed by college students is not significantly less than 99 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 99 liters per year.
