write one or two paragraphs to describe the effects the parameters of a normal curve have on the central location and shape of the curve. You may use the answers to the following two questions as an aid to write your paragraph(s):

1. If the standard deviation of a normal curve remains constant, what effect changes in the mean will have on the curve?
2. If the mean of a normal curve remains constant, what effect changes in the standard deviation will have on the curve?
