P(xbar < 2602.75) =
P(z < (2602.75 - 2552)/(531/sqrt(103) = P(z < 0.97) = 0.8340
Hanna P.
asked 03/06/22The Real Estate Group NY reports that the mean monthly rent for a one-bedroom apartment without a doorman in Manhattan is $2552. Assume the standard deviation is $531. A real estate firm samples 103 apartments.
What is the probability that the sample mean rent is less than $2,602.75?
