Statistics Help

**Question: **We have data on the lean body mass and resting metabolic rate for 12 women who are subjects in a study of dieting.

Lean body mass, given in kilograms, is a person’s weight leaving out all fat.

Metabolic rate, in calories burned per 24 hours, is the rate at which the body consumes energy.

MASS:36.1,54.6,48.5,42,50.6,42,40.3,33.1,42.4,34.5,51.1,41.2

RATE:995,1425,1396,1418,1502,1256,1189,913,1124,1052,1347,1204

31. Make a scatterplot that shows how metabolic rate depends on body mass.

There is a quite strong linear relationship, with correlation r = 0.876.

32. Find the least-squares regression line for predicting metabolic rate from body mass. Add this line to your scatterplot.

Choose the correct equation for the least-square regression line:

A. ŷ = 55.325 + 27.415x

B. ŷ = 1233.71 + 0.032x

C. ŷ = 201.7 + 24.014x

D. ŷ = 201.2 + 24.026x

33. Explain in words what the slope of the regression line tells us.

A. On the average, metabolic rate increases by about 24 calories per day.

B. On the average, metabolic rate increases by about 24 calories per days for each additional kilogram of body mass.

C. On the average, metabolic rate decreases by about 24 calories per day for each additional kilogram of body mass.

D. The estimated metabolic rate for zero mass body is about 24 calories per mass.

\

34. Another woman has lean body mass 45 kilograms. What is her predicted metabolic rate? Use the regression line ŷ = 201.2 + 24.026x and give your answer in cal/day to 2 decimal places. Edit

**Answer: **31.

Please find the attachment for scatter plot .
