4-87.

If you need more help with the mean, median, and mode, refer to the Math Notes box from Lesson 1.3.3 on the right.

It would be helpful to put Leslie's time in order from least to greatest. This will make it easier to analyze the data.

Leslie's running time mean is 238.4 minutes, the median is 238 minutes, and there is no mode.

It may be helpful to know that 4 hours are equal to 240 mintutes.

Try looking closely at the average, or mean, of Leslie's times.

If Leslie did one more practice time and it took her 241 minutes, the mean and median would be greater than those calculated in part (a). Also, there would be a new mode. Does this give you any clues as to how to solve this problem?
