Question:

The square footages and sale prices (in thousands of dollars) of seven homes are shown in the table given below.

Square footage, x Sale price, y

1924 ……………………… 174.9

1592 ……………………… 136.9

2413 ……………………… 275.0

2332 ……………………… 219.9

1552 ……………………… 120.0

1312 ……………………… 99.9

1278 ……………………… 145.0

(a) x = 1450 square feet

(b) x = 2720 square feet

(d) x = 1890 square feet

Find the equation of the regression line for the data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not. If convenient, use technology.
