Consider the normal distribution represented by the normal curve in the figure to the right. (Assume the two labeled values are equidistant from the mean.) Complete parts (a) and (b) below. A normal curve is over a horizontal axis and is centered at the mean. Vertical line segments extend from the horizontal axis to the curve at 80.6, the mean, and 99.4, where 80.6 is to the left of the mean and 99.4 is to the right of the mean. The area under the curve between 80.6 and 99.4 is shaded and contains 95 percent of the data.80.699.4 (a) Find the mean μ
