Given : linear regression equation y = 1.245 x - 3.684
Marquis spent $40 on songs
y = cost
x = songs purchased
To Find : Which is the best estimate of the number of songs that Marquis purchased?
Solution:
y = 1.245 x - 3.684
Marquis spent $40 on songs
=> y = 40
=> 40 = 1.245 x - 3.684
=> 1.245 x = 43.684
=> x = 43.684 / 1.245
=> x = 35.1
Hence
35 is the best estimate of the number of songs that Marquis purchased
