Two surgical procedures are widely used to treat a certain type of cancer. To compare the success rates of the two procedures, random samples of the two types of surgical patients were obtained and the numbers of patients who showed no recurrence of the disease after a 1-year period were recorded. The data are shown in the table. n Number of Successes Procedure A 100 87 Procedure B 100 85 How large a sample would be necessary in order to estimate the difference in the true success rates to within .10 with 95% reliability? O n1 = n2 = 192 O n1 = n2 = 47 On = n2 = 93 On = n = 65Find the critical value Fo for a right-tailed test using a = 0.01, degrees of freedom in the numerator = 3, and degrees of freedom in the denominator = 20.
