To find the mean number of siblings, we need to first calculate the total number of siblings and then divide by the total number of 6th graders surveyed.
Total number of siblings:
0 * 3 = 0
1 * 12 = 12
2 * 5 = 10
3 * 2 = 6
4 * 0 = 0
5 * 1 = 5
Total = 0 + 12 + 10 + 6 + 0 + 5 = 33
Total number of 6th graders surveyed = 3 + 12 + 5 + 2 + 0 + 1 = 23
Mean = Total number of siblings / Total number of 6th graders surveyed
Mean = 33 / 23 = 1.43 siblings
Therefore, the mean number of siblings for the 6th graders surveyed by Kaylen is 1.43 siblings.
Total number of siblings:
0 * 3 = 0
1 * 12 = 12
2 * 5 = 10
3 * 2 = 6
4 * 0 = 0
5 * 1 = 5
Total = 0 + 12 + 10 + 6 + 0 + 5 = 33
Total number of 6th graders surveyed = 3 + 12 + 5 + 2 + 0 + 1 = 23
Mean = Total number of siblings / Total number of 6th graders surveyed
Mean = 33 / 23 = 1.43 siblings
Therefore, the mean number of siblings for the 6th graders surveyed by Kaylen is 1.43 siblings.
