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.

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. $(1\times14)+(2\times16)+(3\times2)+(4\times4)=14 + 32+6 + 16=68$.

Step2: Calculate the total number of households

Sum up the number of households in each category. $14 + 16+2 + 4=36$.

Step3: Calculate the mean

Divide the total number of children by the total number of households. $\frac{68}{36}\approx1.9$.

Answer:

$1.9$
