Question

The p-value is between 0.01 and 0.02
What is your conclusion? Use a = 0.05.
There is a significant relationship between price and overall score
b. Test for a significant relationship using the F test. Use Table 4 of Appendix B.
p-value is between 0.01 and 0.025
What is your conclusion? Use a = 0.05.
Because p-value is less than or equal to
0.05, we reject
Ho B₁ is equal to zero
c. Show the ANOVA table for these data. Round your answers to three decimal places, if necessary. Do not round intermediate calculations.
