Chapter 3.1, Problem 10E

(a)

To determine

Scatterplot for the relationship between lean body mass and metabolic rate.

Explanation of Solution

Given information:

Data on the lean body mass and resting metabolic rate for 12 women:

  

For Scatterplot:

On horizontal axis: Lean body mass

On vertical axis: Metabolic rate

  

(b)

To determine

Relationship between lean body mass and metabolic rate.

Answer to Problem 10E

Linear, positive and moderately strong association without outliers.

Explanation of Solution

Given information:

Data on the lean body mass and resting metabolic rate for 12 women:

  

Strength: Since the points in the scatterplot do not lie closer together but not even spread far apart. Thus, the strength will be moderately strong.

Unusual features: Since there are no points in the scatterplot with strong deviation from the general pattern in the other points. Thus, no outliers exist.

Form: Since in the scatterplot, no strong curvature exists. Thus, the form will be linear.

Direction: Since the pattern in the scatterplot slopes upwards. Thus, the direction will be positive.
