The National Association of Home Builders provided data on the cost of the two most popular home remodeling projects. Sample data on cost in thousands of dollars for two types of remodeling projects are as follows.

Kitchen: 27.0 17.4 22.8 21.9 21.0
Master Bedroom: 18.0 21.1 26.4 24.8 25.4

Kitchen: 23.0 19.7 16.9 21.8 19.0

Master Bedroom: 17.8 24.6 22.0

A. Using Kitchen as population 1 and Master Bedroom as population 2, develop a point estimate of the difference between the population mean remodeling costs for the two types of projects (to 1 decimal).

B. Develop a 90% confidence interval for the difference between the two population means (to 1 decimal).
