Help with stats homework. I’d appreciate it if you’re able to
show work.
I already have part A, so I only need B to
E.
Show transcribed image text HOMEWORK 13 ONLY DO PARTS A-E The following table gives information on the average saturated fats (in grams) consumed per day and the cholesterol level (in milligrams per hundred millimeters) for seven men. Fat Consumption 56 Cholesterol Leve 179 67 220 60 210 49 34 43 185 155 175 246 a) Construct a scatter diagram for these data. Does the scatter diagram exhibit a linear relationship? b) Find the least squared regression line c) Plot the regression line on the scatter diagram of part A and show the errors by drawing vertical lines between scatter points and the regression line d) In our sample, one man had fat consumption of 60 and a cholesterol level 210. What is his predicted cholesterol level? e) Find the error for this observation in part E. f Calculate the standard deviation of errors. g) Compute the coefficient of determination. h) Construct a 90% confidence interval for B i) Test at the 1% significance level whether B is different from zero
