City planners believe that larger cities are populated by older residents. To investigate the relationship, data on population and the median age in 10 large cities were collected.

City Population City
(in millions)
Median age
Chicago, IL 2.833 31.5
Dallas, TX 1.233 30.5
Houston, TX 2.144 30.9
Los Angeles, CA 3.849 31.6
New York, NY 8.214 34.2
Philadelphia, PA 1.448 34.2
Phoenix, AZ 1.513 30.7
San Antonio, TX 1.297 31.7
San Diego, CA 1.257 32.5
San Jose, CA 0.930 32.6
  • Report and interpret the coefficient of determination: ____________%
  • Write the regression equation that predicts median age:       ŷ =___________ + ____________x
  • Slope: 0.272
  • Correlation coefficient: 0.452

I tried to (0.452)^2 = .204304 to get the coefficient of determination and the practice checker is saying it is wrong. Is there a way in excel to do this problem that will be easier?
