Question

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? 1 sibling 2 siblings 3 siblings 4 siblings

Answer 1

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:

$Mean=\dfrac{\text{Sum of observations}}{\text{Number of observations}}$

$Mean=\dfrac{21}{12}$

$Mean=1.75$

Round the population to the nearest unit.

$Mean=2$

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.
