The data shown below for the dependent variable, y, and the independent variable, x, have been collected using simple random sampling. X 30.3 5.5 y 15.9 24.7 9.2 19.5 8.2 12 2.9 29.4 17.5 9.2 23.3 17.9 28.2 28.2 a. Develop a simple linear regression equation for these data. b. Determine the predicted y value when x = 11. c. Estimate the change in the y variable resulting from the increase in the x variable of 12units. d. Conduct a hypothesis test to determine if an increase of 1 unit in the x variable will result in the decrease of the average value of the y variable. Use a significance of 0.025. a. Complete the linear regression equation below. y= 36.42+(-1.08)x (Round to two decimal places as needed.). b. The predicted y value when x = 11 is (Round to two decimal places as needed.)
