Question

To answer the question as to whether or not there is a difference in time to progression, a Chi square statistic is computed. The critical value for rejection of the null hypothesis is 3.84. The computed Chi square is 0.335.;Based on comparing the computed Chi square and the critical Chi square, which of the following is (are) true?;A. There is not statistically significant evidence to show that the time to progression is different between groups.;B. There is statistically significant evidence to show that the time to progression is different between groups.;C. The time to progression is essentially the same for each group.;D. a and c.;The hazard ratio risk of progression to hypertension is 0.658. Based on this computation, which of the following is (are) true?;A. The risk of progression to hypertension is reduced by 34.2% in patients assigned to the new drug as compared to the currently available drug.;B. The risk of progression to hypertension is 1.52 times higher in patient?s current drug as compared to the new drug.;C. The risk of progression to hypertension is 5.12 times higher in patient?s current drug as compared to the new drug;D. a and b
