- What is the effect of measurement error in Y? How is this different fromthe effect of measurement error in X?when z =\2.5, x = 42.1 ando = 2 %3D determine u = ZIn a sample analysis with 50 respondents, we wanted to study the relationship between the number X of minutes spent listening to music and the listening time Y of a specific radio, again expressed in minutes, on a summer weekend day. The findings are that: 50 50 žXi=6000, Eyi=3700, Sx=125, sy=105 and rxy=0.75, i=1 j = 1 where Sx, Sy respectively. The estimated standard error of the regression is also equal to se=20. and ryy are the sample standard deviation of X, Y and the sample linear correlation coefficient between X and Y Estimate the simple linear regression model that explains the variable Y as a function of X. Report the required values in the spaces below.

How does lateral acceleration—side forces experienced in turns that are largely under driver control—affect nausea as perceived by bus passengers? An article reported data on x = motion sickness dose (calculated in accordance with a British standard for evaluating similar motion at sea) and y = reported nausea (%). Relevant summary quantities are n = 17, xi = 223.9 , yi = 196 , xi2 = 3056.65 , xiyi = 2759.6 , yi2 = 2976 . Values of dose in the sample ranged from 6.0 to 17.6. (a) Assuming that the simple linear regression model is valid for relating these two variables (this is supported by the raw data), calculate and interpret an estimate of the slope parameter that conveys information about the precision and reliability of estimation. (Calculate a 95% CI. Round your answers to three decimal places.) , (b) Does it appear that there is a…
