Question

A study is made of working couples. The regression equationfor predicting wife's income from husband's income is wife's income= 0.1667 *husband's income +$24000 another investigator solves this equation for husband'sincome, and gets husband's income= 6*wife's income -$144000 True or false, and explain: the secondinvestigator had found the regression equation for predictionhusband's income from wife's income. If you want to computeanything, husband's average income = $54000, sd=39000 wife's average income = $33000, sd=$26000 , r=0.25 A study is made of working couples.
