Note on Homework 9

On the second part of the homework the statement reads

We have a sample of size n = 23, an average of x-bar = 87.6 and a standard deviation sx = 7.8.

The questions that follow ask for thresholds for 95% and 99% confidence both low and high. This is really asking you to look up numbers on Table A-3 on the salmon sheet, and you have more than enough information to do that with the statistics given.
