Question

A research report on a prospective study states that: “A comparison of the 90 normal patients with the 50 patients with hypotension shows that only 3.33% of the former group died as compared to 30% of the latter.”

(a) Calculate the sample odds ratio, construct a 95% confidence interval, and provide an interpretation

(b) Test the significance of blood pressure as a prognostic sign using Pearson's Chi-Squared Test. Be sure to provide the following: 

  • Define the parameter(s) of interest.
  • State the null and alternative hypotheses.
  • State the significance level.
  • State what type of test you will perform and why you chose to use the test.
  • State and check any necessary assumptions. Check assumptions by hand showing all calculations.
  • State your test statistic and its null distribution.
  • Give the output of the hypothesis test from R. Verify the calculation of the test statistic by hand.  You do not have to verify the P-value by hand. 
  • State the decision rule.
  • State your conclusion in the context of the problem. Be sure to include the P-value.
