Joe has two routes he can drive to work. He wants to learn which route is the fastest. The time to drive each route varies a little every day.Joe assumes that each route will be open and safe to drive. Over the next two weeks Joe alternated driving the two routes. He timed the length of his drive on each route.He calculated the mean and standard deviation of the times for both routes. Route 1Route 2Mean25.2 minutes25.8 minutesStandard Deviation1.8 minutes8.9 minutes Which route has the possibility of a very short amount of time to drive to work? Which route results in the most consistent times? Which route is more likely to take a very long time on occasion? Group of answer choicesRoute 1, Route 2, Route 1Route 1, Route 2, Route 2Route 2 on all the answersRoute 1 on all the answersRoute 2, Route 1, Route 2Route 2, Route 2, Route 1Route 2, Route 1, Route 1

Suppose the commute times for employees of a large company follow a normal distribution. If the mean time is 22 minutes and the standard deviation is 5 minutes, 95% of the employees will have a travel time within which range?A.17.25 minutes to 26.75 minutesB.17 minutes to 27 minutesC.12 minutes to 32 minutesD.7 minutes to 37 minutesSUBMITarrow_backPREVIOUS

Dave drives to work each morning at about the same time. His commute time is normally distributed with a mean of 50 minutes and a standard deviation of 6 minutes.  What percentage of the time will his commute time be greater than 58 minutes?

An analyst has timed a metal-cutting task for 50 cycles. The average time per cycle was 11.9 minutes, and the standard deviation was 1.32 minutes for a worker with a performance rating of 130 percent. Assume an allowance of 17 percent of task time. Calculate the standard time for this task. (Do not round intermediate calculations. Round the final answer to 2 decimal places.)

The following data represents the daily commute times (in minutes) of 8 employees in a company: 15, 20, 25, 30, 35, 40, 45, 50.Calculate the mean deviation from the mean commute time.*2 pointsThe mean deviation from the mean commute time is 10 minutes.The mean deviation from the mean commute time is 11 minutes.The mean deviation from the mean commute time is 12 minutes.The mean deviation from the mean commute time is 13 minutes.

Public transportation and the automobile are two alternatives an employee can use to get to work each day. Samples of times recorded for each alternative are shown below. Times are in minutes.Public transportation:  28 29 32 37 33 25 29 32 41 34Automobile:         29 31 33 32 34 30 31 32 35 33  A. Compute the sample mean for both alternatives.B. Compute the sample standard deviation for both alternatives.C. Based on your results from part (a) and (b), which alternative should be preferred?
