Question

Given are five observations for two variables, x and y .

xi	1	2	3	4	5
yi	53	58	47	21	11

Use the estimated regression equation is y-hat = 78.01 - 3.08x

A.) Compute the mean square error using equation.

s^2 = MSE = SSE / n -2

[     ]   (to 2 decimals)

B.) Compute the standard error of the estimate using equation

s = sqrtMSE = sqrt SSE / n - 2

[      ] (to 2 decimals)

C.) Compute the estimated standard deviation of b1 using equation.

sb1 = s / sqrt ( xi - x-bar )^2

[       ] (to 4 decimals)

D.) Use the t -test to test the following hypotheses (a=.05 ):

H0 = B1 = 0

Ha = B1 ≠ 0

Compute the value of the -test statistic (Enter negative values as negative numbers). [          ] (to 4 decimals)

THE P-VALUE IS: [ Less than .01, * between .01 and .02, * .02 and .05, * .05 and .10, * .10 and .20, * .20 and .40, * Greater than .40. ]

What is your conclusion? [ DO NOT REJECT ; REJECT ] Ho
