(b) Use a = 0.01 to test for a significant relationship. State the null and alternative hypotheses. O Ho: b1 = b2 = 0 Ha: One or more of the parameters is not equal to zero. O Ho: One or more of the parameters is not equal to zero. Ha: b1 - b2 = 0 O Ho: One or more of the parameters is not equal to zero. Ha: bo = b1 = b2 = 0 O Ho: bo = b1 = b2 = 0 Ha: One or more of the parameters is not equal to zero. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value = What is your conclusion? O Do not reject Ho. We conclude that the relationship is significant. O Reject Ho. We conclude that the relationship is significant. O Reject Ho. We cannot conclude that the relationship is significant. O Do not reject Ho. We cannot conclude that the relationship is significant.
