(a)Use technology to find the estimates of 0 and 1.

0 b0 =

1 b1 =

(round to two decimal places)

(b) Use technology to compute the standard error, the point estimate for .

se =

(c) Assuming the residuals are normally distributed, use technology to determine sb1.

sb1=

(d) Assuming the residuals are normally distributed, test H0: 1 = 0 versus H1: 1 0 at the = 0.05 level of significance.

Use the P-value approach.

H0: 1 = 0 H1: 1 0 =

Determine the P-value for this hypothesis test.

P-value =
