Question

Transcribed Image Text:**Title: Hypothesis Testing on Alcohol Consumption**
The average American consumes 100 liters of alcohol per year. Researchers surveyed 75 randomly selected college students and found that the average college student consumes a different amount of alcohol per year, with a standard deviation of 16 liters. What can be concluded at the 0.05 level of significance?
**Steps for Hypothesis Testing:**
a. **Study Type**: Select the appropriate test for this study.
b. **Hypotheses**: Define null (H₀) and alternative (H₁) hypotheses.
**Hypotheses Format**:
- H₀ (Null Hypothesis): The population mean amount of alcohol consumed by college students is not significantly different from 100 liters per year.
- H₁ (Alternative Hypothesis): The population mean amount of alcohol consumed by college students is significantly different from 100 liters per year.
c. **Test Statistic (Z or t)**: Calculate the test statistic value rounded to three decimal places.
d. **p-value**: Determine the p-value from the test statistic.
e. **Decision**: Compare the p-value with α (0.05) to decide whether to reject or fail to reject the null hypothesis.
**Conclusion**:
Based on the statistical evidence, determine whether there is significant evidence to conclude that college students’ average alcohol consumption differs from the standard population mean of 100 liters per year.
**Options**:
- If there is no significant evidence of difference at α = 0.05, do not reject the null hypothesis.
- If there is significant evidence of difference at α = 0.05, reject the null hypothesis.
