a. Does the t test indicate a significant relationship between price and the overall score?
The test t-Conclusion at a = .05
t =
4.74
(to 2 decimal places.)
p-value is less than .01
What is your conclusion? Use a = .05.
There is a significant relationship between price and overall score
b. Test for a significant relationship using the F test.
p-value is less than .01
What is your conclusion? Use a = .05.
Because p-value is less than or equal to
.05, we reject
Ho: B 1 is equal to zero
c. Show the ANOVA table for these data. Round your answers to three decimal places, if necessary.
