A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: ý = bo + bịx bo = 36.465 - 1.082 b1 - 0.646 Use this to predict the number of situps a person who watches 2.5 hours of TV can do (to one decimal place)
A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y).The results of the regression were:y=ax+b a=-0.649 b=20.136 r2=0.488601 r=-0.699 Use this to predict the number of situps a person who watches 2.5 hours of TV can do (to one decimal place)

In 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. (Report 3 decimal places) (Manual correction question) -The estimated intercept of the model: -The estimated slope of the model: -The 95% confidence interval for the model slope: Write down on the answer sheet all the calculations needed to arrive at the required values.
A student in PSYC 227 class collects data for a class project. She asks 10 classmates to shoot 10 free throws on a standard basketball court and records the number of shots made by each participant (X). She also has these same participants run an obstacle course and records their time (Y). She wants to statistically evaluate if variables X and Y are related. She computes the sum of squared deviations for X, the sum of squared deviations for Y, and the sum of cross products between X and Y.
