Refer to the accompanying data set on wait times from two different line configurations. Assume that the sample is a simple random sample obtained from a population with a normal distribution. Construct separate $99\%$ confidence interval estimates of $?$ using the two-line wait times and the single-line wait times. Do the results support the expectation that the single line has less variation? Do the wait times from both line configurations satisfy the requirements for confidence interval estimates of $?$ ?
