Please see attached excel spreadsheet for data set on lean body mass and resting metabolic rate for 19 individuals. Then, could you help me with the following three questions:

1. Refer to the excel spreadsheet labeled Data for Exercise 3.4. Place the data on an Excel spreadsheet and use the chart wizard to construct a scatter plot of the data for the female subjects. Which is the explanatory variable?

3. Does the pattern of relationship that you observed in the female subjects hold for men also? How do the male subjects as a group differ from the female subjects as a group?
