Question 2 Not yet answered Marked out of 10 P Flag question A random sample was taken of the wait times for licensing customers at the Massachusetts RMV branches in Roslindale and Watertown. The following statistics were compiled from these samples (all times measured in minutes): Watertown: Mean = 31.4, SD = 5.5 Roslindale: Mean = 25.8, SD = 5.2 Compute the coefficients of variation for the wait times at the Watertown and Roslindale RMV branches. (Round your answers to two places past the decimal point.) Which branch has the greater variability in wait times? Question 3 Not yet answered Marked out of 10 Flag question As part of the same survey as in Question 2, the wait times of licensing customers at the Massachusetts RMV branch on Washington Street in Boston were collected and found to have a mean of 29.6 minutes and a standard deviation of 8.7 minutes. Classify each of the following wait times as "within the average range", "above/below average but not unusually high/low", or "unusually high/low". (If your answer is one of these last two, be sure to specify whether the time is above or below average.) Explain your answers in each case. (a) 47.4 minutes (b) 21.2 minutes (c) 38.9 minutes
