a. Does the t test indicate a significant relationship between price and the overall score?

The test -Conclusion at (alpha)=.05

t= _________ (to 2 decimal places.)

t-value is - Select your answer -less than .01, between .01 and .025, between .025 and .05, between .05 and .1, greater than .1

What is your conclusion? Use (alpha =.05) .
- Select your answer -There is a significant relationship between price and overall score, There is no significant relationship between price and overall score

p-value is - Select your answer -less than .01, between .01 and .025, between .025 and .05, between .05 and .1, greater than .1

What is your conclusion? Use (alpha =.05) .

Because p -value is - Select your answer -greater than or equal to, less than or equal to, equal to 0.05 , we - Select your answer -accept, reject H0:B1 is - Select your answer -greater than or equal to zero, less than or equal to zero, equal to zero

c. Show the ANOVA table for these data. Round your answers to three decimal places, if necessary.

Source of Variation	Sum of Squares	Degrees of Freedom	Mean Square	F	p-value
Regression					- Select your answer -less than .01, between .01 and .025, between .025 and .05, between .05 and .1, greater than .1
