x: 20 30 40 50 60

y: 100 97 93 83 72

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

0b0=

(Round to two decimal places asneeded.)

1b1=

(Round to two decimal places asneeded.)

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

se=

(Round to four decimal places asneeded.)

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

sb1=

(Round to four decimal places asneeded.)

(d) Assuming the residuals are normallydistributed, test H0:1=0 versus H1:10 at the =0.05 level of significance. Use theP-value approach.

Determine theP-value for this hypothesis test.

P-value=

(Round to three decimal places asneeded.)

Which of the following conclusions iscorrect?

A.

Reject H0 and conclude that a linear relation doesnotexist between x and y.

B.

Donotreject H0 and conclude that a linear relation doesnotexist between x and y.

C.

Donotreject H0 and conclude that a linear relation exists between x and y.

D.

Reject H0 and conclude that a linear relation exists between x and y.
