Question

Suppose a magazine would like to investigate the relationship between the battery? life, in? hours, and the screen? size, in diagonal? inches, of a laptop computer. The accompanying table shows a random sample of eight laptops and the battery life and corresponding screen size of each. Use this information to complete parts a through e below.

Battery Life (x)= 3.4, 3.9, 3.9, 3.9, 3.1, 3.8, 4.7, 3.9

Screen size (y)= 15.1, 17.4, 14.1, 12.1, 14.1, 13.4, 11.3, 12.7

a)correct scatter plot

b)Calculate the slope and? y-intercept for the regression equation.

c)Provide an interpretation for the value of the slope.

d)Calculate the SST

e)Partition the SST into the SSR and the SSE.
