Problems

Note: For each of the following problems, you can either compute the requested statistics by-hand, or use R. I recommend using R, and saving all of your work in an R Notebook.

Example: Suppose you were asked to compute the mean of the numbers: 1, 2, 3.

In R, you would first store these numbers in a vector x using:

x = c(1, 2, 3)

The 'c' is short for 'concatenate,' and tells R to combine all of the values you pass as arguments into a single vector.

Then compute the mean of x using:

mean(x)
