ReviewName192101) A paint manufacturer wanted to compare the drying times of two different types of paint. Independent simple isamples of 11 cans of type A and 9 cans of type B were selected and applied to similar surfaces. The drying timehours, were recorded. The summary statistics are as follows.2Туре A| Туре ВX1 = 70.9 x2 = 68.1$13.3n₁ = 11Determine a 99% confidence interval for the difference between the mean drying time of type A and the mean.ctime of type B. Suppose the normal probability plots of samples of type A and B are roughly staright lines.APR28$2= 3.4n₂ = 92) The principal randomly selected six students to take an aptitude test. Their scores were:71.3 83.3 78.7 87.7 84.6 80.5Determine a 99% confidence interval for the mean score for all students. Note the normal probability plot is rougstraight line.NO Atv♫MacBook Air
