Suppose that men's mean heartrate is 75.4 beats per minute (bpm), and women's mean heartrate is 78.4 bom. Both have a standard deviation of 3.6 bom. Madison randomly polls 30 men and 30 women. 1. What is the mean of the distribution of sample mean differences? Find E( men bom - X women bom ) . bom 2. What is the standard deviation of the distribution of sample mean differences? Find SD (X men bom - women bom). Round your answer to 2 decimals. bomEvery year, the students at a school in Boston are given a musical aptitude test that gives scores from 0 percent to 100 percent.
