The given table describes a random sample of 30 houses sold in a Midwest city during a recent year.14 We will examine the relationship between size and price.

You need to find out if r² suggests that size is quite helpful for predicting selling price.

Fill in the blank. (Give your answer to one decimal place.)

The value of r² in percent is :

Solution

Using technology, we get the correlation,              
              
r =    0.656166038          
              
Thus, the coefficient of determination is              
              
r^2 =    0.43055387 = 43.1% [ANSWER]
