In the main directory from which you start MINITAB session
put first the following MTB files:

 pinf.MTB
 pinft.MTB
 pinft1.MTB
 pinft2.MTB 
 pinft3.MTB  

Start minitab and exec macros.

The mtb session should look like: 

 MTB > exec 'pinf'
 Executing from file: pinf.MTB

 Please enter the confidence LEVEL that you're
 interested in.  (For example, you would enter 95
 if you want to produce a 95% c.i.)
 DATA> 95

 Please enter the SAMPLE SIZE (n) and then the number
 of "yes" responses (or "successes") on the same line.
 DATA> 700 294

   The sample proportion is p-hat =  0.4200


   The critical value is z-star =   1.960


   The half-width of the 95.00% confidence interval is    0.037


   The 95.00% confidence interval for theta is ( 0.383, 0.457)


 MTB > exec 'pinft'
 Executing from file: pinft.MTB

 Please enter the HYPOTHESIZED value of
 the population proportion (theta_0).
 DATA> 0.45

 Please enter the code to specify the ALTERNATIVE hypothesis H_a:
 enter 1 if H_a has the form: theta < theta_0
 enter 2 if H_a has the form: theta > theta_0
 enter 3 if H_a has the form: theta - theta_0
 DATA> 3

 Please enter the SAMPLE SIZE (n) and then the number
 of "yes" responses (or "successes") on the same line.

 DATA> 700 294

   The sample proportion is p-hat =  0.4200

 Executing from file: pinft3.MTB

   For testing the null hypothesis H_0: theta =  0.4500


    vs. the alternative hypothesis H_a: theta -  0.4500


   The test statistic is z =  -1.595


   The p-value of the test is  0.1106
