To construct the scatterplot based on the provided data, we need to plot the average times against the ages of the runners. Here's the actual data you provided:

  • For age 24, the time is 32.75 minutes.
  • For age 29, the time is 33.63 minutes.
  • For age 34, the time is 34.84 minutes.
  • For age 39, the time is 35.33 minutes.
  • For age 44, the time is 35.23 minutes.
  • For age 49, the time is 36.16 minutes.

The corresponding points to plot are:

  • (24, 32.75)
  • (29, 33.63)
  • (34, 34.84)
  • (39, 35.33)
  • (44, 35.23)
  • (49, 36.16)

Now, looking at the options provided, we need a coordinate plane that accurately represents this data.

  1. The x-axis should represent age in years. The relevant range from the data is 24 to 49.
  2. The y-axis should represent time in minutes. The relevant range from the data is from about 32.75 to 36.16.

Among the given options, the second choice matches more closely with the requirement of plotting the age against the time. Though there may be some inaccuracies in the exact values provided in the point descriptions, it is important to select the option which has:

  • Age on the x-axis (from 0 to 40)
  • Time on the y-axis (from 0 to 40) which captures effectively the age values.

Thus, the second option would be the most appropriate as it seems to provide the right frame for plotting age against average time.

Answer: The second option matches most closely with the requirements for plotting the scatterplot.
