A medical researcher wants to determine if a two month jogging program will reduce the resting pulse rate of women aged 40-50. A random sample if 6 women provided the following results on resting pulse rates before and after the program. Before: 98,83,74,92,74,62. After: 90,79,70,89,71,54. Test at the 1% significance level whether the jogging program reduced rating pulse rates. Formulate and test the appropriate hypothesis. Assume population of paired differences has a normal distribution. Use the critical value approach.
