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?

No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low. B. 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. OC. 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. OD. No, because the frequencies start at a maximum and become low, and because the distribution is not symmetric. Examine the data and identify anything appearing to be unique. Select all that apply. A. The data are presented as quantitative but are actually categorical. B. Most of the data values are rounded to the nearest 5 or 10 minutes, and may be estimates of actual commute times. C. The unusually large value of 80 minutes appears to be an error in recording the data. D. Based on the gaps in the distribution, the data appear to be from two different populations.

Do the data amounts appear to have a normal distribution?
OA. No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low.
B. 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.
OC. 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.
OD. No, because the frequencies start at a maximum and become low, and because the distribution is not symmetric.
Examine the data and identify anything appearing to be unique. Select all that apply.
A. The data are presented as quantitative but are actually categorical.
B. Most of the data values are rounded to the nearest 5 or 10 minutes, and may be estimates of actual commute times.
C. The unusually large value of 80 minutes appears to be an error in recording the data.
D. Based on the gaps in the distribution, the data appear to be from two different populations.
