MY NOTES ASK YOUR TEACHER A paper describes a study to determine the effects of several keyboard characteristics on typing speed. One of the variables considered was the front-to-back surface angle of the keyboard. Minitab output resulting from fitting the simple linear regression model with x = surface angle (degrees) and y = typing speed (words per minute) is given below. Regression Analysis: Typing Speed versus Surface Angle The regression equation is Typing Speed = 60.0 + 0.0036 Surface Angle Predictor Constant Surface Angle -0.511766 Coef 60.0286 0.00357 R-Bq=0.3% Analysis of Variance SE Coef T 0.2466 0.03823 243.45 0.09 0.0000 0.9315 R-Bq (adj) = 0.0% Bource DF 85 Regression 1 0.0023 Residual Error Total 3 0.0023 0.7857 0.2619 F 0.01 0.9315 4 0.788 (a) Assuming that the basic assumptions of the simple linear regression model are reasonably met, carry out a hypothesis test using a = 0.05 to decide if there is a useful linear relationship between x and y. What is the test statistic. tm What is the P-value for this test? P-value= What can you conclude? Fail to reject Ho. We have convincing evidence of a useful linear relationship between typing speed and surface angle. Fall to reject Ho. We do not have convincing evidence of a useful linear relationship between typing speed and surface angle O Relect H
