Statistics Programs
This routine initializes the normal distribution program.
Stores default value for mean.
Prompts for and stores mean, M .
Stores default value for standard deviation.
Prompts for and stores standard deviation, S .
Stops displaying value of standard deviation.
This routine calculates Q ( X ) given X .
Prompts for and stores X .
Calculates upper tail area.
Stores value in Q so VIEW function can display it.
Displays Q ( X ).
Loops to calculate another Q(X).
This routine calculates X given Q ( X ).
Prompts for and stores Q ( X ).
Recalls the mean.
Stores the mean as the guess for X , called X
This label defines the start of the iterative loop.
Calculates ( Q ( X
