To find the average number of points scored during the 2004 season, add up all the scores and divide by the total number of scores. The average number of points scored during the 2004 season is approximately 79.87.
To calculate the average number of points scored during the 2004 season, we need to add up all the values in the stem-and-leaf plot and divide the sum by the total number of values.
Based on the given stem-and-leaf plot, the scores range from 60 to 99. We have the following scores in the 60s: 62, 64, 65, 65, 68. In the 70s: 70, 72, 72, 74, 75, 75, 75, 76, 78, 78, 81. In the 80s: 83, 83, 84, 85, 87, 88. And in the 90s: 92, 95, 98, 98, 100, 100.
Now, we add up all the scores and divide by the total number of scores: (62 + 64 + 65 + 65 + 68 + 70 + 72 + 72 + 74 + 75 + 75 + 75 + 76 + 78 + 78 + 81 + 83 + 83 + 84 + 85 + 87 + 88 + 92 + 95 + 98 + 98 + 100 + 100) / 31 = 79.87.
The average number of points scored during the 2004 season is approximately 79.87.
