Please answer...it's due soon, it's 50 points..! The first table shows the measures of variability for finish times of 30 runners in the 100-meter dash. Calista’s finish times are recorded in the second table. She cannot tell which number is for which year. Based on the data table, when did Calista likely record Finish Time A? Explain.

Last Year's Running Time Mean: 16.2s

Last year's MAD: 1.2

This Year's Running Time Mean: 14.7s

This year's MAD: 1.9

A- This year, because finish times were less last year, on average, as compared to last year.

B- Last year, because finish times were less last year, on average, as compared to this year.

C- This year, because finish times were greater last year, on average, as compared to last year.

D- Last year, because finish times were greater last year, on average, as compared to this year.
