For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer < = ≠ > H1:H1: ? μ p Select an answer > < ≠ = The test statistic ? z t = (please show your answer to 3 decimal places.)

Thus, the final conclusion is that ... The data suggest the populaton mean is significantly more than 92 at αα = 0.01, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is more than 92 liters per year. The data suggest that the population mean amount of alcohol consumed by college students is not significantly more than 92 liters per year at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is more than 92 liters per year. The data suggest the population mean is not significantly more than 92 at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is equal to 92 liters per year.

Question

The average American consumes 92 liters of alcohol per year. Does the average college student consume more alcohol per year? A researcher surveyed 14 randomly selected college students and found that they averaged 104.7 liters of alcohol consumed per year with a standard deviation of 15 liters. What can be concluded at the the αα = 0.01 level of significance?

For this study, we should use Select an answer t-test for a population mean z-test for a population proportion
The null and alternative hypotheses would be:

H0:H0: ? p μ Select an answer < = ≠ >

H1:H1: ? μ p Select an answer > < ≠ =

The test statistic ? z t = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? > ≤ αα
Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the populaton mean is significantly more than 92 at αα = 0.01, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is more than 92 liters per year.
- The data suggest that the population mean amount of alcohol consumed by college students is not significantly more than 92 liters per year at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is more than 92 liters per year.
- The data suggest the population mean is not significantly more than 92 at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is equal to 92 liters per year.
