When estimating a multiple regression model based on 30 observations, the following results were obtained. When estimating a multiple regression model based on 30 observations, the following results were obtained. a. Specify the hypotheses to determine whether x<sub>1 </sub>is linearly related to y. At the 5% significance level, use the p-value approach to complete the test. Are x<sub>1 </sub>and<sub> </sub>y linearly related? B) Construct the 95% confidence interval for β<sub>2</sub>. Using this confidence interval, is x<sub>2 </sub>significant in explaining y? Explain. C) At the 5% significance level, can you conclude that β<sub>1</sub> differs from −1? Show the relevant steps of the appropriate hypothesis test. a. Specify the hypotheses to determine whether x1 is linearly related to y. At the 5% significance level, use the p-value approach to complete the test. Are x1 and y linearly related?
