Step 1
The total number of children is calculated by multiplying the number of children by the number of families for each row and then adding them up. So, (1*6) + (2*22) + (3*14) = 6 + 44 + 42 = 92 children. The total number of families is 6 + 22 + 14 = 42 Show more…

A simple random sample of 50 families has produced the following statistics: Number of children in the family (x): mean = 2.1, standard deviation = 1.4 Annual Gross Income (y): mean = 34,250, standard deviation = 10,540 r = 0.75 The linear regression equation relating these variables based on the data of this study is Number of children = 5,646 (income) + 22,392 Number of children = 22,392 (income) + 5,646 Income = 34,350 + .0001 (number of children) Income = .0001 (number of children) - 1.312 Income = 5,646 (number of children) + 22, 392
