In a regression analysis involving 27 observations, the following estimated regression equation was developed. = 25.2 + 5.5x1 For this estimated regression equation SST = 1,550 and SSE = 590. (a) At a = 0.05, test whether x is significant. State the null and alternative hypotheses. O Ho B #0 Ha B =0 | Ho: Bo = 0 Ha: Po 0 O Ho: Po 0 Ha Bo=0 Ho: B =0 B1 Ha B1 0 Find the value of the test statistic. (Round your answer to two decimal places.) F= 40.68 Find the p-value. (Round your answer to three decimal places.) p-value 0.000 Is x significant? Reject Ho. We conclude that x is significant. O Do not reject Ho. We conclude that x is not significant. Do not reject Ho. We conclude that x is significant. Reject Ho. We conclude that x is not significant. 1
