The estimated regression equation for this data is ŷ = 21.588629 +0.334114x, where x = price ($) and y = overall score. Does the t test indicate a significant relationship between price and the overall score? Use α = 0.05. State the null and alternative hypotheses. Ho: Po +0 H₂: Po = 0 Ho: B₁ = 0 ○ Mo: B₁ = 0 H₂ P₁ = 0 OH ₁₂ 20 H₂: B₁ <0 o Hoi Bo = 0 Ha: Po 0 Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value= What is your conclusion? Do not reject Ho. We conclude that the relationship between price ($) and overall score is significant. Reject Ho. We conclude that the relationship between price ($) and overall score is significant. Do not reject Ho. We cannot conclude that the relationship between price ($) and overall score is significant. Reject Ho. We cannot conclude that the relationship between price ($) and overall score is significant. Test for a significant relationship using the F test. Use α = 0.05. State the null and alternative hypotheses. H: B=0
