Dear Tutor,I asked you about this question but I think it got some troubles with your solution. Would you mind to help me solve it again?5–57. Residential real estate in New York rents for an average of $44 per square foot, for a certain segment of the market.14 If the population standard deviation is $7, and a random sample of 50 properties is chosen, what is the probability that the sample average will be below $35?5–58. In problem 5–57, give 0.95 probability bounds on the value of the sample mean that would be obtained. Also give 0.90 probability bounds on the value of the sample mean.Regards.
