You will need to "compute the values" yourself, but I see one thing to include in your comments: Both $75 and $100 are within the "standard deviation of $22." What do you think that means?

Z = (score-mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z scores.

Then you can comment.
