The average American consumes 91 liters of alcohol per year. Does the average college student consume a different amount of alcohol per year? A researcher surveyed 15 randomly selected college students and found that they averaged 72 liters of alcohol consumed per year with a standard deviation of 23 liters. What can be concluded at 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: Ho: ? Select an answer v H1: ? v Select an answer c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that... (Please show your answer to 4 decimal places.) The data suggest the populaton mean is significantly different from 91 at a = 0.01, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is different from 91 liters per year. O The data suggest that the population mean amount of alcohol consumed by college students is not significantly different from 91 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 different from 91 liters per year. O The data suggest the population mean is not significantly different from 91 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 91 liters per year.

Question
Transcribed Image Text:The average American consumes 91 liters of alcohol per year. Does the average college student consume a
different amount of alcohol per year? A researcher surveyed 15 randomly selected college students and
found that they averaged 72 liters of alcohol consumed per year with a standard deviation of 23 liters.
What can be concluded at 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:
Ho: ? v
Select an answer v
H: ? v | Select an answer v
c. The test statistic ?
(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 different from 91 at a = 0.01, so there is
statistically significant evidence to conclude that the population mean amount of alcohol
consumed by college students is different from 91 liters per year.
O The data suggest that the population mean amount of alcohol consumed by college students is
not significantly different from 91 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 different from 91 liters per year.
The data suggest the population mean is not significantly different from 91 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 91 liters per year.
