When estimating a multiple regression model based on 30 observations, the following results were obtained. a. Specify the hypotheses to determine whether x₁is linearly related to y. At the 5% significance level, use the p-value approach to complete the test. Are x₁andy linearly related?
B) Construct the 95% confidence interval for β₂. Using this confidence interval, is x₂significant in explaining y? Explain.
C) At the 5% significance level, can you conclude that β₁ differs from −1? Show the relevant steps of the appropriate hypothesis test.
