a paint manufacturer wishes to compare the drying times of two different types of paint. independent random samples of 11 cans of type a and 9 cans of type b were selected and applied to similar surfaces. the drying times (in hours) were recorded. the summary statistics are as follows. type a type b sample mean 77.3 hrs 63.7 hrs sample sd 4.5 hrs 5.1 hrs sample size 11 9 the manufacturer then uses this data to test the claim that the mean drying time for type a differs from the mean drying time for type b. a 1% significance level is used. assume that both populations are approximately normally distributed and that the population variances are not equal. what is the p-value for the test? group of answer choices 0.000011 1.095 0.5475 0.0011
