Consider the building inspector's visits once again. Suppose now that 15 new built houses are selected at random for inspection. Remember that the inspector knows from past experience that 8 out of every 10 new built houses complies with municipal regulations. What is the variance of the number of new built houses that will comply with municipal regulations? a. 2.40 b. 1.55 c. 2.56 d. 1.60 e. 2.72

New Homes A contractor has four new home plans. Plan 1 is a home with six windows. Plan 2 is a home with seven windows. Plan 3 has eight windows, and plan 4 has nine windows. The probability distribution for the sale of the homes is shown. Find the mean, variance, and standard deviation for the number of windows in the homes that the contractor builds. $$ \begin{array}{c|cccc}{X} & {6} & {7} & {8} & {9} \\ \hline P(X) & {0.3} & {0.4} & {0.25} & {0.05}\end{array} $$

The number of days it takes to build a new house has a variance of 386. A sample of 40 new homes shows an average building time of 83 days. With what confidence can we assert that the average building time for a new house is between 80 and 90 days? A. 15.4% B. 17.8% C. 20.0% D. 38.8% E. 82.1%
