The average American consumes 100 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 86 liters of alcohol consumed per year with a standard deviation of 16 liters.
What can be concluded at the the a = 0.05 level of significance?
a. For this study, we should use t-test for a population mean
b. The null and alternative hypotheses would be:
Ho:
H₁: #
v 100
v 100
c. The test statistic tv = -3.389 (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 ? a
f. Based on this, we should
g. Thus, the final conclusion is that ...
Select an answer the null hypothesis.
O The data suggest the populaton mean is significantly different from 100 at a = 0.05, so there
is statistically significant evidence to conclude that the population mean amount of alcohol
consumed by college students is different from 100 liters per year.
O The data suggest the population mean is not significantly different from 100 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 100 liters per year.
O The data suggest that the population mean amount of alcohol consumed by college students is
not significantly different from 100 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 different from 100 liters per year.
