**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.

13% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those who live in the inner city have sleep apnea. Of the 324 people from the inner city surveyed, 32 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.01? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: Ho: ? p μ ? = < > ≠ (please enter a decimal) H1: ? μ p ? ≠ < > = (Please enter a decimal) The test statistic ? t z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤ αα Based on this, we should Select an answer accept fail to reject reject the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly smaller than 13% at αα = 0.01, so there is sufficient evidence to…

9 K Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6210 patients treated with this drug, 151 developed the adverse reaction of nausea. Use a 0.10 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: p=0.03 H₁: p=0.03 OB. Ho: p*0.03 H₁: p=0.03 O C. Ho: p=0.03 H₁: p>0.03 OD. Ho: p=0.03 H₁: p<0.03 Identify the test statistic for this hypothesis test.
