Size (ounces)	Cost ($)
16	3.59
32	4.49
64	5.29
200	10.19

Is the least squares line valid for predicting what a 300-ounce size of the laundry detergent would cost? Why or why not?

Select one:

a. The least squares line is not valid for predicting the cost of a 300-ounce container of detergent because the cost would be unreasonable.

b. The least squares line is not valid for predicting the cost of a 300-ounce container of detergent because 300 ounces is beyond the range ofx-values.

c. The least squares line is valid for predicting the cost of a 300-ounce container of detergent because it is possible to purchase 300 ounces.

d. The least squares line is valid for predicting what a 300-ounce container of laundry detergent would cost because all equations can be used to make predictions.
