Monthly Mortgage Payments The average monthly mortgage payment including principal and interest is $982 in the United States. Assume that the standard deviation is approximately $180 and the mortgage payments are approximately normally distributed. Find these probabilities of the monthly payment selected olo randomly. Enter the final answers as decimals rounded to at least four places. Round intermediate z-value calculations to two decimal places. Part: 0 / 2 Part 1 of 2 (a) More than $1270 P(X > 1270) = X 5Heart Rates For a certain group of individuals, the average heart rate is 71 beats per minute. Assume the variable is normally distributed and the standard deviation is 3 beats per minute. If a subject is selected at random, find the probability that the person has the following heart rate. Round the final answers to at least four decimal places and intermediate z-value calculations to two decimal places. Part: 0 / 3 Part 1 of 3 (a) Between 67 and 73 beats per minute P(67
