### According to www.umich.edu-isaincominghousing.html, in 2007 the mo.pdf

1. According to www.umich.edu/-isa/incoming/housing.html, in 2007 the monthly rental rates for one bedroom apartments in Ann Arbor, Michigan, had a mean of \$700. Suppose those rental rates have approximately a normal distribution, with a standard deviation of \$150. Using a table, calculator, or software that can give normal probabilities, find the approximately proportion of one-bedroom apartments for which the rental rate: is a least \$1000 a month. Is less than \$500 a month. Is between \$500 and \$1000 a month. Solution Given X~Normal(mean=700, s=150) a. P(X>1000)=P((X-mean)/s > (1000- 700)/150) =P(Z>2) = 0.0228 (check standard normal table) b. P(X<500)=P(Z<(500-700)/150) =P(Z<-1.33) =0.0918 c. P(500
