Type your answers to the questions in the text box below, making sure to reference the relevant part of the output in each answer. (6 points) Perform a hypothesis test at significance level 0.05 to determine whether at least one of the predictors in the 6-predictor model is useful in predicting Y. Write the null and alternative hypotheses, the value of the test statistic and p-value, the decision rule, and your conclusion. (8 points) Perform a hypothesis test at significance level 0.05 to determine whether predictors X4, X5, and X6 are significantly linearly related to Y upon controlling for predictors X1, X2, and X3. Write the null and alternative hypotheses, the value of the test statistic and p-value, the decision rule, and your conclusion.
