Ateacher wants to estimate the mean time (in minutes) that students take to go from one classroom to the next. his research assistant uses the sample time of 42 students to report the confidence interval as [7.40, 8.60]. [you may find it useful to reference the t table.] a. find the sample mean time used to compute the confidence interval. (round intermediate calculations to 4 decimal places and final answer to the nearest whole number.) b. determine the confidence level if the sample standard deviation used for the interval is 1.606. (round intermediate calculations to at least 4 decimal places. round "t" value to 3 decimal places and final answer to the nearest whole number.)
