Question

In the triple-jump competition, Lee jumped 28 ft, 32 ft, 29 ft, 30 ft, and

33 ft.
a. Find the mean, median, mode, and range of Lee's marks.

Answer 1

• Mean = 30.4

• Median = 30

• Mode = None

• Range = 5

Explanation:

To find the mean, we add all the numbers together and divide by the total number of numbers. In this case, we have 5 numbers: 28, 32, 29, 30, and 33. Adding them together gives us 152. Dividing by 5 gives us a mean of 30.4.

To find the median, we need to order the numbers from smallest to largest: 28, 29, 30, 32, and 33. The median is the middle number which is 30.

To find the mode, we look for the number that appears most frequently in the list. In this case, there is no number that appears more than once so there is no mode.

To find the range, we subtract the smallest number from the largest number. In this case, the smallest number is 28 and the largest number is 33 so the range is 5.

Therefore:

• Mean = 30.4

• Median = 30

• Mode = None

• Range = 5

I hope that helps!
