408 Chapter 9: The Normal Probability Distribution
One can now use the Normal Probability Distribution workbook with the
computed mean, standard deviation, and X = 274.5. The results are shown
in Figure 9-44 below. Thus P( X > 274.5) = 0.0368.
Figure 9-44: Normal Probability for P(X > 274.5) = 0.0368
Alternatively, one can use the Normal Approximation to the Binomial
workbook. The results are shown in Figure 9-45 below.
