How do I set up the code for #5? I have 1-4 computed fine. Would it be

> Sum(height) / length (length) ?

Define the following vectors, which represent the weight and height of people on a

particular team (in inches and pounds):

height <- c(59,60,61,58,67,72,70)

weight <- c(150,140,180,220,160,140,130)

Define a variable:

a <- 150

Step 1: Calculating means

1) Compute, using R, the average height (called mean in R

2) Compute, using R, the average weight (called mean in R)

3) Calculate the length of the vector height and weight

4) Calculate the sum of the heights

5) Compute the average of both height and weight, by dividing the sum (of the height

or the width, as appropriate), by the length of the vector. How does this compare to

the mean function?
