Stаte whether belоw stаtement is either а True оr a False statement. If it is false, explain why. Please nоte that you can say something is true if it’s always true. Suppose we are testing the effectiveness of two drugs A and B in timely pain relief. Drug A was tested on a random sample of 20 patients, and has mean relief time of 10.3 minutes with standard deviation of 2.2 minutes. Drug B was tested on another 20 patients, and has mean relief time 8.3 minutes and standard deviation of 2.8 minutes. Based on our "rule of thumb", we cannot use the pooled estimate of the standard error.
