The average monthly mortgage payment for all homeowners in a city is $2910. Suppose that the distribution of monthly mortgages paid by homeowners in this city follow an approximate normal distribution with a mean of $2910 and a standard deviation of $470. Find to 4 decimal places the probability that the monthly mortgage paid by a randomly selected homeowner from this city is a. less than $1200. Probability = b. more than $3500. Probability = c. between $2200 and $3260. Probability = d. between $3100 and $3700. Probability
