While at summer camp, Mike asked a random camper from each of the 12 cabins how many siblings he or she had. The results below display the responses.

3, 2, 0, 1, 0, 2, 3, 4, 1, 2, 2, 1

If there are 48 campers altogether, use Mike’s data to infer the mean of the population. What is the mean number of siblings for the population rounded to the nearest unit?

The mean number of siblings in the sample will be an estimate of the mean number of siblings in the population.
$$\large \bar{x}=\frac{3+2+0+1+0+2+3+4+1+2+2+1}{12}=you\ can\ calculate$$
