Answer:
A. The data for store 1 shows greater variability.
C. The mean of the data for store 1 is greater than the mean of the data for store 2.
Explanation:
I took the test and got this question right.
A. The data for store 1 shows greater variability.
This is the data for store 1: 16, 28, 36, 40, 78
This is the data for store 2: 22, 27, 33, 36, 40
The range on store 1 is 62, but the range for store 2 is only 18. So store 1 has more variability because the numbers are more spread out.
C. The mean of the data for store 1 is greater than the mean of the data for store 2.
The mean of Store 1's data set [16, 28, 36, 40, 78] is 39.6
The mean of Store 2's data set [22, 27, 33, 36, 40] is 31.6
As you can see, 39.6 is greater than 31.6.
