A clincial trial examined whether a certain drug X increases the heart rate in 105 diabetics. The following 2 x 2 contingency table displays the results of the trial: Heart Rate Increased No Heart Rate Increase Total Treated with drug X 36 14 50 Not treated with drug X 29 26 55 Total 65 40 105 1. Calculate the Chi-square test statistic from the data. 2. What are the degrees of freedom in this case? 3. Look up the p-value for this test using the Chi-square table provided in this week's PowerPoint presentation (you will not be able to find the exact p-value from the table, but two values between which the actual p-value lies). 5. Interpret your results, i.e., is the p-value significant at the 5% level (alpha = 0.05)? What is your conclusion about the effect of the drug X on heart rate in diabetics? Show all your calculations
