Question

Two weeks in a row, the golf course hosts a group of golfers. The second week had 10 more golfers than the first week. Use the dot plots to choose the true statement.

A. The range for Week 1 equals the range for Week 2.
B. The range for Week 1 is greater than the range for Week 2.
C. The median for Week 1 is less than the median for Week 2.
D. The mean for Week 1 is greater than the mean for Week 2.

Answer 1

The true statement is: A. The range for Week 1 equals the range for Week 2.

Explanation:

Let's recall that the range of a data set is the difference between the largest number and the smallest number.

As we can confirm in the plot for week 1, the range is:

Range for week 1 = Largest number - smallest number

Range for week 1 = 89 - 62 = 27

In the same way, we can confirm in the plot for week 2 that the range is:

Range for week 2 = Largest number - smallest number

Range for week 2 = 89 - 62 = 27

Ranges for week 1 and 2 are equal, thus,

The true statement is: A. The range for Week 1 equals the range for Week 2.
