u may need to use the appropriate technology to answer this question. a regression analysis involving 27 observations, the following estimated regression equation was developed. y = 25.2 + 5.5x1 or this estimated regression equation SST = 1,550 and SSE = 590. At a = 0.05, test whether x, is significant. State the null and alternative hypotheses. O Ho: Bo = 0 Ha : Po # 0 OH : B 1 = 0 Ha : B 1 = 0 OH : Bo = 0 Ha : Po = 0 OHo : B 1 = 0 Ha : P 1 = 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 = Is x, significant? O Reject Ho. We conclude that x, is significant. O Do not reject Ho. We conclude that x] is not significant. O Reject Ho. We conclude that x, is not significant. O Do not reject Ho. We conclude that x, is significant. Suppose that variables x, and x? are added to the model and the following regression equation is obtained
