Problem 129E
A primer paint can be used on aluminum panels. The primer’s drying time is an important consideration in the manufacturing process. Twenty panels are selected, and the drying times are as follows: 1.6, 1.3, 1.5, 1.6, 1.7, 1.9, 1.8, 1.6, 1.4, 1.8, 1.9, 1.8, 1.7, 1.5, 1.6, 1.4, 1.3, 1.6, 1.5, and 1.8. Is there evidence that the mean drying time of the primer exceeds 1.5 hr?
