Stаte whаt the given cоnfidence intervаl suggests abоut the twо population means.A paint manufacturer made a modification to a paint to speed up its drying time. Independent simple random samples of 11 cans of type A (the original paint) and 9 cans of type B (the modified paint) were selected and applied to similar surfaces. The drying times, in hours, were recorded. The summary statistics are as follows. The following 98% confidence interval was obtained for the difference between the mean drying time for paint cans of type A and the mean drying time for paint cans of type B: What does the confidence interval suggest about the population means?
