Question

Computer software give a chi-square statistic of 0.124 for a test with 15 degrees of freedom. The p-value is found to be: A) less than 0.05 B)between 0.05 and 0.1 C) greater than 0.1

A randomized double-blind clinical trial found that 5.4% of subjects in the angioplasty with eptifibatide group and 9.2% in the angioplasty with placebo group died or experienced another heart attack within 48 hours of treatment. The relative risk, RR, is A) 0.587 B)0.413 C) 0.704

A couple multiple choice questions I want to make sure I got the right answer on to compare.

Answer 1

(1) p-value = . Hence, greater than 0.1.

(2) RR = 5.4%/9.2% = 0.054/0.092 = 0.587.
