Question

The variables are (from right to left) Age (years), Weight (kg), Oxygen intake rate (ml per kg body weight per minute), time to run 1.5 miles (minutes), heart rate while resting, heart rate while running (same time Oxygen rate measured), and maximum heart rate recorded while running. The sample file noted that certain values of MaxPulse were changed for this analysis.  The data for sas are below:

1.) Use PROC MEANS to create an output dataset containing only the means of all numeric variables with Age as a classification variable. How many observations are in this output dataset?

2.)  Use PROC TABULATE to create the five number summary: minimum, first quartile, median, third quartile, and maximum with the summary statistics in the column and the variables as rows.

What is the maximum oxygen intake rate for people who ran a mile over 7 min?
