The approximate probability density function for the normal distribution (the bell curve) is given below for a mean of 0 and a standard deviation 1. P(x) = 0.4 e −0.5x 2 Use Excel or Google Sheets to construct left-endpoint, right-endpoint, and midpoint approximations of the area under the curve for the intervals below using n rectangles. Why are the left-endpoint and right-endpoint approximations the same? (a) [−1, 1], n = 8 (Proportion of the data within one standard deviation of the mean) (b) [−2, 2], n = 16 (Proportion of the data within two standard deviations of the mean)
