The Census Bureau gives this distribution for the number of people in American households in 2016.Family size1246.7Proportion0.280.350.150.130.060.020.01Note: In this table, 7 actually represents households of size 7 or greater. But for purposes of this exercise, assume that itmeans only households of size exactly 7.How many people are represented in your sample of 4000 households?(Hint: The number of individuals in your sample who live in households of size 7 is 7 times the number of households of size 7.Repeat this reasoning to determine the number of individuals in households of sizes 2 to 6. Add the results to get the totalnumber of people represented in your sample.)There areindividuals represented in the sample of 4000 households.
