2. The scatter plot below shows the relationship between the number of members in a family and the amount of the family's weekly grocery bill.
A. Write a line of best fit.
_____________________________
B. The most appropriate prediction of the grocery bill for a family that consists of six members is
1) $100
2) $300
3) $400
4) $500
A. To write a line of best fit, we need to determine the equation of the line that most closely approximates the relationship between the number of members in a family and the amount of the family's weekly grocery bill. We can do this by using linear regression.
B. Unfortunately, we cannot provide an accurate prediction for the grocery bill of a family with six members without seeing the scatter plot or having more information about the relationship between the number of members and the grocery bill.
