Question
The average American consumes 86 liters of alcohol per year. Does the average college student consume more
alcohol per year? A researcher surveyed 11 randomly selected college students and found that they averaged
95.8 liters of alcohol consumed per year with a standard deviation of 20 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 O
b. The null and alternative hypotheses would be:
Ho: μ =
H₁: μ >
O 86
O 86
c. The test statistic (t) =
d. The p-value =
e. The p-value is ? a
f. Based on this, we should Select an answer the null hypothesis.
g. Thus, the final conclusion is that ...
1.625 (please show your answer to 3 decimal places.)
(Please show your answer to 4 decimal places.)
O The data suggest the population mean is not significantly more than 86 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 86 liters per year.
The data suggest that the population mean amount of alcohol consumed by college students is
not significantly more than 86 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 more than 86 liters per year.
The data suggest the populaton mean is significantly more than 86 at a = 0.05, so there is
statistically significant evidence to conclude that the population mean amount of alcohol
consumed by college students is more than 86 liters per year.
