Extracted text: The following data give the times of 15 girls when they were put on ultraheavy rope-jumping program. Someone thought that such a program would increase their speed in the 40-yard dash. Let D equal the different in time run the 40-yard dash – the "before program time (x)" minus the "after-program time (v)". Assume that the distribution of D is approximately normal, N(µp, o). Test the null hypothesis Ho: Hp = 0 against the alternative hypothesis H1: µp > 0.
