Question

Does the data provide sufficient evidence to indicate that mortage interest rates affect the annual number of existing single-family homes sold?

x-bar= 10.68 , y-bar= 3125.3
SSxx=32.116
SSxy=-7926.54
SSyy= 2,166,654.1

Answer 1

r^2 = (SSxy)^2/SSxxSSyy
r^2 = (7926.54)^2/((32.116)(2,166,654.1))
r^2 = 0.90293
r = 0.95023
This indicates a pretty good correlation
