(4) In estimating the mean drive time (in minutes) of employees at IBM, we use an original sample of size n = 100 and a bootstrap distribution containing 3000 bootstrap samples to obtain a 95% confidence interval of (30.2, 51.7). In each of the following, a change in this process is described. If all else stays the same, which of the following confidence intervals (A, B, or C) is the most likely result after the change: A. (25.6, 56.3) B. (30.2, 51.7) C. (33.5, 48.4) (a) Using the data to find a 99% confidence interval. (b) Using the data to find a 90% confidence interval. (c) Using an original sample of size n = 200. (d) Using an original sample of size n = 50
