* The following code will carry out inferential tasks concerning
* \mu  and  \sigma. ;

* Chapter 6 tasks: Obtain 95% confidence intervals for  \mu  and  
* \sigma  assuming normality.  [The lower and upper limits of the 
* latter confidence interval are just the square roots of the lower 
* and upper limits of the confidence interval for  \sigma^2.] ;

* Chapter 7 tasks: Test H_0: \mu = \mu_0  vs.  H_1: \mu \ne \mu_0, 
* assuming normality.  In this example, \mu_0 = 5. ;
