Consider the following set of ordered pairs. 3 5 Y 5 8 5 6 a. Using ix = D.10, test for the significance of the regression slope. b. Construct a 90% confidence interval for the population slope. a. Using ix = 0.10, test for the significance of the regression slope. Identify the null and alternative hypotheses. Hg: P Hy: 14 Find the test statistic. 1= (Round to two decimal places as needed.) Find the p-value. p-value = (Round to three decimal places as needed.) State the conclusion. the null hypothesis. There is evidence to conclude that the regression slope b. Construct a 90% confidence interval for the population slope. UCL = LOL = (Round to two decimal places as needed.)
