Question 22

Short Answer

Consider the following data.
Consider the following data. A) Calculate the least squares estimate . B) Calculate the least squares estimate . C) Estimate the error variance . D) Test H<sub>0</sub>: \beta <sub>1</sub> = 0 versus H<sub>1</sub>: \beta <sub>1</sub> \neq 0 with \alpha = 0.05. Answer H<sub>0</sub> is rejected at \alpha = 0.05 or H<sub>0</sub> is not rejected at \alpha = 0.05 . E) Estimate the expected y value corresponding to x = 3. F) Give a 90% confidence interval for the expected y value at x = 3. Round your answer to two decimal places. Consider the following data. A) Calculate the least squares estimate .
