A grocery store wants to examine the relationship between the sales amounts each day at two different locations, store A and store B. The sales amount each day, in dollars, was recorded for 10 days at each store. The least-squares regression line is y-hat=-3,000 + 1.2x, where x represents the sales
amounts each day at store A and y represents the sales amounts each day at store B. If the mean of the 10 sales amounts for store B is 545,000, what is
the mean of the 10 sales amounts for store A?
O $42.000
O $35.000
O $51,000
O $45,000
O $40,000
