Question: Manufacturing and Product Development The tear strength, tensile strength, backing, and thickness all contribute to the durability of vinyl wallpaper. A new company (Aries Wallcoverings) claims to sell the thickest vinyl wallpaper of any currently on the market. Independent random samples of Aries wallpaper and all others were obtained. The thickness of each wallpaper (in inches) was measured. Assume the underlying distributions are normal, with unequal variances. Is there any evidence to support the claim made by Aries Wallcoverings? Use a = 0.01.
