A2)

A paint manufacturer wants to compare the drying times of two different colors of paint. Independent random samples of 10 cans of Eggshell and 10 cans of Ecru were selected and applied to similar surfaces. The drying times (in hours) were recorded. The data are below. Conduct the appropriate test and determine which, if either, paint you would purchase based on the faster drying time:

Eggshell:67889075748291857775

Ecru:68677289777379857270

a. Eggshell dried significantly faster than Ecru.

b. Ecru dried significantly faster than did Eggshell.

c. Not enough information to decide.

d. There were no differences between Eggshell and Ecru
