A constructor decided to build homes that will include the middle 80% of the market. If the average size of the homes built is 1810 square feet, find the maximum and minimum size of the homes the constructor should build.

Step 1

The middle 80% is that 40% to the right of the mean and the 40% to the left of the mean.

Hence, the upper limit by using Excel function =Norm.S.INV(0.90) is 1.2816 and the...
