Question

In a crash test, 11 cars were tested to determine what impact speed was required to obtain minimal bumper damage. Find the mode of the speeds given in miles per hour below.

24, 15, 18, 20, 18, 22, 24, 26, 18, 26, 24

• A. 15 -20
• B. 10-15
• C. 0-5
• D. 5-10

Answer 1

Answer: (A), (C)

The correct options are
A

15 -20

C

0-5

Ordering the data from least to greatest, we get:

15, 18, 18, 18, 20, 22, 24, 24, 24, 26, 26

Since both 18 and 24 occur three times, the modes are 18 and 24 miles per hour. This data set is bimodal.
