A pharmaceutical company claims that if a blood pressure drug is taken properly, the amount of blood pressure decrease will be normally distributed with a mean equal to 10 points on the diastolic reading and a standard deviation equal to 4.0. One hundred patients were administered the drug, and data were collected showing the reduction in blood pressure at the end of the test period. The data are in the file labeled Blood Pressure.

Using a goodness-of-fit test and a significance level equal to 0.05, what conclusion should be reached with respect to the distribution of diastolic blood pressure reduction? Discuss.
