Draw a number line on which adjacent tick marks are 0.1 unit apart and on which 0.003 can be plotted (in its approximate location). Now show how to “zoom in” on smaller and smaller portions of the number line (see Activity 1.3- Zooming In and Out) until you have “zoomed in” to a portion of the number line in which adjacent tick marks are 0.001 apart and so that 0.003 can be plotted on each number line. Label the longer tick marks on each number line, and plot 0.003 on each number line (in its approximate location).

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.

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…
