You can use the program with any normally distributed population tor which
you know the mean and standard deviation
1 Store the mean in memory 3 and the standard deviation in memory 4
2 Store the lower limit in memory 1 and the upper limit in memory 2.
3 Presa Gafin.
4 Enter the number of intervals and press R/S When the computation
ends, you can view the result
S. To use the program lor different limits, repeat steps 2 through 4
Calculate the integral tor the limits of 69 5 to 79.5 and 89.5 to 100. using
nine intervals for each integration
