Answer:
Option 2.
Step-by-step explanation:
It is given that Mike asked a random camper from each of the 12 cabins how many siblings he or she had.
The given data set is
3, 2, 0, 1, 0, 2, 3, 4, 1, 2, 2, 1
Sum of observations = 3+2+0+1+0+2+3+4+1+2+2+1=21
Number of observations = 12
Formula for mean:
Round the population to the nearest unit.
We have to use Mike’s data to infer the mean of the population. So, the mean of sample is equal to the mean of population.
The mean number of siblings for the population is 2 siblings.
Therefore, the correct option is 2.
