An experiment is designed to be analyzed by a paired t-test (i.e., a t-test for matched samples) at the 95% confidence level. A small number of samples were collected before and after a treatment (n = 4 pairs) and the data analyzed by paired t-test, yielding a p-value of 0.049 such that the null hypothesis was rejected and the alternative was accepted that there was a significant treatment effect. A. What type of statistical error might have been made, and B. What might be done to reduce the probability of this statistical error
