A coordinate plane is titled: Average Time of a 5 K. It shows age in years on the x-axis from 0 to 40 in increments of 2 and time in minutes on the y-axis from 0 to 50 in increments of 5.
The approximate data points are as follows: left parenthesis 33 comma 24 right parenthesis, left parenthesis 34 comma 29 right parenthesis, left parenthesis 35 comma 34 right parenthesis, left parenthesis 35 comma 39 right parenthesis, left parenthesis 35 comma 44 right parenthesis, and left parenthesis 36 comma 49 right parenthesis.

To construct a scatterplot based on the data provided in the table, we need to plot the following points according to their age and average time:

  • Age 24, Time 32.75
  • Age 29, Time 33.63
  • Age 34, Time 34.84
  • Age 39, Time 35.33
  • Age 44, Time 35.23
  • Age 49, Time 36.16

Given this data, we look for the correct scatterplot option:

  1. X-axis (Age in years) should be represented from 0 to 50, with increments that make it clear to identify the age points.
  2. Y-axis (Time in minutes) should cover a range from below 32.75 (the minimum) to above 36.16 (the maximum), for instance, from 30 to 40 in suitable increments.

None of the options you provided seem to accurately reflect the data given:

  • The incorrect coordinates and scaling on the X and Y axes are seen in all options presented.

The best approach would be to ideally have a scatterplot where:

  • The points plotted are:
    • (24, 32.75)
    • (29, 33.63)
    • (34, 34.84)
    • (39, 35.33)
    • (44, 35.23)
    • (49, 36.16)

If you have a scatterplot in mind or you can create a graph, ensure that the axes are correctly labeled and scaled accordingly.

If faced with just the given options, none would represent the data accurately. You could create a new scatterplot or find an option that fits more closely with the true values from the table.
