Question

the table below summarizes the number of children per household for a sample of 32 families. what is the mean number of children per household for these families? round your answer to the nearest tenth. table: number of children per household: 2, 3, 4; number of households: 14, 16, 2

Explanation:

Step1: Calculate the total number of children

Multiply the number of children per household by the number of households for each category and sum them up. $(14\times2)+(16\times4)+(2\times3)=28 + 64+6=98$.

Step2: Calculate the total number of households

Sum up the number of households in each category. $2 + 4+3=9$.

Step3: Calculate the mean

Divide the total number of children by the total number of households. $\frac{98}{9}\approx10.9$.

Answer:

$10.9$
