A study was conducted that was focused on the cost of groceries. As part of the study, the researchers gathered data from families with anywhere from 2 to 5 people and recorded how much they spent on groceries each month. Afterwards they calculated the least squares regression line to model the amount of money spent on groceries each month (Y) based on the number of people in their family (X). The regression line they calculated was: Y = 726 + 125X If appropriate, utilize the regression line to predict the amount of money spent on groceries each month by a family of 9.
