If the population standard deviation is 4.2 breaths per minute for jogging and 4.5 breaths per minute for walking, test the claim that the breathing rate for jogging is more than the breathing rate for walking. Assume a = 0.055. Let the breathing rates of joggers represent population 1 and the breathing rate of walkers represent population 2. a.)
