Add to ORKGThe paper concerns testing the hypothesis about the mean H0:[mu]=[mu]0 against the one-sided alternative in normal populations. For the sample size n=4(1)20, two-sided 95% confidence intervals are given for the probability that the test of size 0.05 detects the difference [Delta]=[mu]-[mu]0.Student's t-test Power of the test Confidence interval
