Question 2 You are proctoring a test for class A and decide to measure the length of time it takes each person to finish. These times are given below. # Run this cell times.A = c(44.84, 44.17, 38.2, 45.2, 38.83, 47.38, 42.36, 38.1, 36.51, 35.1, 35.52, 33.43, 44.86, 43.49, 39.85) Part A) Calculate the 95% confidence interval for on, the true standard deviation for the time it takes to take the test. Define this interval such that 2.5% of the area is lower than the lower bound and 2.5% of the area is above the upper bound. Save the bounds of your confidence interval as p2. a. lower and p2 . a . upper . Round your answers to 2 decimal places. times.A
