The average American consumes 99 liters of alcohol per year. Does the average college student consume a different amount of alcohol per year? A researcher surveyed 10 randomly selected college students and found that they averaged 91.9 liters of alcohol consumed per year with a standard deviation of 23 liters. What can be concluded at the the = 0.10 level of significance?

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

H0:H0: ? p Select an answer = > <

H1:H1: ? p Select an answer < = >

1. The test statistic ? z t = (please show your answer to 3 decimal places.)
2. The p-value = (Please show your answer to 4 decimal places.)
3. The p-value is ? >
4. Based on this, we should Select an answer reject accept fail to reject the null hypothesis.
5. Thus, the final conclusion is that ...

• The data suggest the population mean is not significantly different from 99 at = 0.10, 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 the populaton mean is significantly different from 99 at = 0.10, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is different from 99 liters per year.
• The data suggest that the population mean amount of alcohol consumed by college students is not significantly different from 99 liters per year at = 0.10, so there is statistically insignificant evidence to conclude that the population mean amount of alcohol consumed by college students is different from 99 liters per year.
