State whether below statement is either a True or a False statement. If it is false explain why. Please note 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.
