In a study of the relationship between marble ownership and household income, the Grinch
interviewed a simple random sample of 160 Who-Households, and generated the following summary
statistics:
x = 4.2
Sx = 0.7
ỹ = 15.6
Sy = 2.8
Ixy = 0.825
where
Xi =
monthly income of the ith household, measured in $1000s.
Yi =
weight of marbles owned by ith household, measured in Ibs .
Using these statistics to find the regression equation for predicting marble weight from income, the
estimated mean weight of marbles owned by all Who-households with monthly incomes of $3000
is..
O= 13.28 lbs
O 11.64 lbs
= 9.9 Ibs
= 8.7 Ibs
