Kaylen wants to know how many siblings 6th graders. She surveys the 6th graders on her soccer team. Her results are given in the table. What is the mean number of siblings for the 6th graders that she surveyed? Round your answer to the nearest hundredth. Number of siblings : 0, 1, 2, 3, 4, 5. Number of 6th graders: 3, 12, 5, 2, 0, 1.
To find the mean number of siblings for the 6th graders that Kaylen surveyed, we first need to calculate the total number of siblings and the total number of 6th graders surveyed.
Total number of siblings:
(0 * 3) + (1 * 12) + (2 * 5) + (3 * 2) + (4 * 0) + (5 * 1)
= 0 + 12 + 10 + 6 + 0 + 5
= 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
= 33 / 23
= 1.43
Therefore, the mean number of siblings for the 6th graders that Kaylen surveyed is 1.43 (rounded to the nearest hundredth).
