What are the SAS codes to produce the predicted values table for simple regression? The data is called superfood. Y is the dependent variable and X is the independent variable.

3- What are the SAS codes to produce the predicted values table for simple regression? The data is called superfood. Y is the dependent variable and X is the independent variable.

a) proc corr data = superfood; run;

b) proc reg data = superfood;

model Y = X/clb;

run;quit;

c) proc reg data = superfood;

model Y = X/p;

run;quit;

d) proc reg data = superfood;

model X = Y/p clm;

run;quit;

e) proc reg data = superfood;

model Y = X;

run;quit;

4- What are the SAS codes to produce the 90% Confidence Interval around the parameter estimates (b_o and b₁) for simple regression? The data is called superfood. Y is the dependent variable and X is the independent variable.

a) proc reg data = superfood;

model Y = X/p;

run;quit;

b) proc reg data = superfood alpha = 0.10;

model Y = X/p clm;

run;quit;

c) proc reg data = superfood;

model Y = X/p cli;

run;quit;

d) proc reg data = superfood alpha = 0.10;

model Y = X/clb;

run;quit;

e) proc reg data = superfood alpha = 0.10; run;quit;

5- We would like to predict the height (in inches) of supermodels based on their weight (in pounds). Using the SAS output provided choose the incorrectalternative. The fitted regression line is: y(hat) = 10.77 + 1.60 height
