The accompanying data are 45 commute times to work in minutes for workers of age 16 or older in Chicago. Construct a frequency distribution. Use a class width of 15 minutes and begin with a lower class limit of 0 minutes. Do the data amounts appear to have a normal distribution? Examine the data and identify anything appearing to be unique. Click the icon to view the commute times. X

Question
The accompanying data are 45 commute times to work in minutes for workers of age 16 or older in Chicago. Construct a frequency distribution. Use a class width of 15 minutes and begin with a lower class limit of 0 minutes. Do the data amounts appear to have a normal distribution? Examine the data and identify anything appearing to be unique. Click the icon to view the commute times. Construct the frequency distribution. Commute Time (minutes) 0- L Frequency (Type whole numbers.) Do the data amounts appear to have a normal distribution? Commute Times 60 30 60 15 35 30 12 30 30 15 28 30 10 4 12 45 20 20 20 30 Print 15 45 45 20 60 30 15 45 80 45 10 15 15 25 45 30 45 30 35 60 30 25 Done 15 D A. The data are presented as quantitative but are actually categorical. B. Based on the gaps in the distribution, the data appear to be from two different populations. C. Most of the data values are rounded to the nearest 5 or 10 minutes, and may be estimates of actual commute times. D. The unusually large value of 80 minutes appears to be an error in recording the data. 20 30 X O A. No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low. O B. ause frequencies start at and become low, the distribution t symmetric. O C. No, because while the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, the distribution is not symmetric. O D. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric. Examine the data and identify anything appearing to be unique. Select all that apply.
