Question
The following is a scatterplot of SALES regressed on CATALOGS. The regression equation is: estimated SALES=247.0745+78.6075*CATALOGS R-square= .2175 SALES $8,000 $7,000 $6,000 $5,000 $4,000 $3,000 $2,000 $1,000 SALES vs. CATALOGS SALES 247.1 78.61*X R: 0.218 $0 4 6 8 10 12 14 16 18 20 22 24 26 CATALOGS SALES SALES If 22 catalogs were sent to a household, what would be the estimated amount of sales? Since the dependent variable is in dollars, use 2 decimal places in your answer and use the proper rules of rounding. Do not put the dollar sign in your answer!
