  • 9. Write a paragraph summarizing the results of the analysis in Exercise 8. What can you conclude about smoking and depression (“Feeling Down”) in this sample? The Chi-square value of 6.31 is statistically significant because it is greater than its critical value of 5.99. In addition, the p-value is less than 0.05, therefore we can reject the null hypothesis that smokers/non-smokers are independent of the depression frequency. It appears that smoking affects depression frequency. 10. Be...

  • 5. (1 pt) Write a few sentences that could be used to report the results obtained for the t-test in Exercise 4. We are unable to reject the null hypothesis (H0: μ = 45) because the p-value 0.1371 is greater than .05 makes it non-significant. The tabled value 2.12 for a two-tailed test is greater than the t-statistic 1.565. This means we cannot accept the alternative hypothesis that the drug alters heart rate. (HA : μ ≠ 45) 6.
