Show your work for any parts where you are asked to compute BY HAND.

I want to see the R-code used for each part. DO NOT show all of 
the output, just the relevant pieces to answer the questions. 
Cut and paste *relevant* R commands and output into a word 
processor such as MS Word. 

DO NOT INCLUDE OUTPUT THAT YOU DO NOT REFER TO OR USE IN THE PROBLEM, 
otherwise points will be deducted.


Problem 4 uses data from "ch05q02.txt" (QUET & AGE)
---------
4a) State an interpretation for each of the statistics. 
4b) Compute the 99% CI using R. 
    
Problem 10 uses data from "ch05q06.txt" (ATST & AGE)
----------
10a) State an interpretation for each of the statistics. 
10b) No change from the text. 
10c) Compute BY HAND the 95% CI for .5*ln((1+rho)/(1-rho)) & transform to get a CI for rho.

Problem 14
----------
14a) Compute BY HAND. Also, include a p-value for the test.
14c) Skip this part.
