The data shows the number of seconds it took two randomly selected groups to thread a needle. Compare the measures of center and variability of these data sets.

Student Group A: 56, 14, 26, 28, 29, 45, 32, 80, 3, 10
Student Group B: 27, 24, 18, 19, 5, 16, 22, 10, 6, 20

Which of the following statements about these data sets is false?

(1 point)

The mean time taken by Group A is higher than that of Group B.

The ranges of the time taken by Group A and Group B are the same.

The amount of variability of the time taken by Group A to thread a needle is higher than the amount of variability of the time taken by Group B.

The median time taken by members of Group A to thread a needle is higher than that of members of Group B.

The false statement is: "The ranges of the time taken by Group A and Group B are the same."

Calculations:
- Mean A = 323/10 = 32.3, Mean B = 167/10 = 16.7 (A > B).
- Median A = (28+29)/2 = 28.5, Median B = (18+19)/2 = 18.5 (A > B).
- Range A = 80 − 3 = 77, Range B = 27 − 5 = 22 (not the same).
- Variability (spread) for A is larger than B (e.g., larger range and more spread around the mean).

So the range statement is false.
