Answer:
The mean of the data set is:
18.5
Explanation:
The data values are given as:
Done Game Pitches Seen
1 25
2 20
3 20
4 17
5 15
6 14
We know the mean of the data set is calculated as the average of the data values.
Hence, here the mean of the data set is ratio of the total number of pitches to the total number of games.
Total number of pitches=25+20+20+17+15+14=111
Number of games=6

Hence, Mean of the data set= 18.5
