In a regression analysis involving 27 observations, the following estimated regression equation was developed. ŷ = 25.2 + 5.5x₁ For this estimated regression equation SST = 1,500 and SSE = 530. (a) At a = 0.05,
test whether X1 is significant. State the null and alternative hypotheses. OH₁: B₁ = 0 H₂: B₁ * 010 Ho: B₁ 0 H₂: B₁ = 0 0 Ho: Po = 0 Ha: Bo #0 Ọ Ho: Bo #0 Ha: Po = 0 Find the value of the test statistic. (Round
your answer to two decimal places.) F = Find the p-value. (Round your answer to three decimal places.) p-value = ls X₁ significant? O Do not reject Ho. We conclude that x₁ is not significant. O Do not reject Ho.
We conclude that x₁ is significant.
