Pls Answer ASAP!!

Souta wants to compare the mean of his test scores in French class to the mean absolute deviation. He uses the steps below to find both the mean and mean absolute deviation.

French Scores

Step 1

Add the scores.

76 + 62 + 94 + 80 = 312

Step 2

Divide the sum of the scores by 4.

312 divided by 4 = 78

Step 3

Add the differences between the mean and each score.

(76 minus 78) + (62 minus 78) + (94 minus 78) + (80 minus 78) = 0

Step 4 Divide by 4.

StartFraction 0 over 4 EndFraction = 0

In which step did Souta make the first error?

1.Step 1

2.Step 2

3.Step 3

4.Step 4

Teams of 4 are competing in a 1/4 mile relay race. each runner must run the same exact distance. what is the distance each teammate runs?
