(c) Perform a t test for the significance of ₁. Use α = 0.05. State the null and alternative hypotheses. Ho: B₁ * 0 Ha: B₁ = 0 O 0 Ho: B₁ = 0 H₂: B₁ * 0 O O O Find the value of the test statistic. (Round your answer to two decimal places.) t = Ho: B₁ <0 Ha: B₁ ≥ 0 Find the p-value. (Round your answer to three decimal places.) p-value= O Ho: P₁ = 0 Ha: B₁ > 0 State your conclusion. O Do not reject Ho. There is sufficient evidence to conclude that ₁ is significant. O Reject Ho. There is insufficient evidence to conclude that ₁ is significant. O Reject Ho. There is sufficient evidence to conclude that is significant. O Do not reject Ho. There is insufficient evidence to conclude that B₁ is significant. O Ho: B₁ > O H₂: B₁ ≤0 (d) Perform a t test for the significance of ₂. Use α = 0.05. State the null and alternative hypotheses.
