[AI-generated answer — Bot GPT 3.5]

To find the mean number of siblings for the 6th graders surveyed by Kaylen, we need to calculate the total number of siblings and then divide by the total number of 6th graders surveyed.

Number of siblings:
0 siblings x 3 = 0
1 sibling x 12 = 12
2 siblings x 5 = 10
3 siblings x 2 = 6
4 siblings x 0 = 0
5 siblings x 1 = 5

Total number of siblings = 33

Total number of 6th graders surveyed = 3 + 12 + 5 + 2 + 0 + 1 = 23

Mean number of siblings = Total number of siblings / Total number of 6th graders surveyed
Mean number of siblings = 33 / 23 = 1.43 siblings

Therefore, the mean number of siblings for the 6th graders surveyed by Kaylen is 1.43 siblings.
