4-20. The equation for a Gaussian curve is 1 -(x-1)/20 V2TT In Excel, the square-root function is SQRT and the exponential function is EXP. To find e 3.4, write EXP(-3.4). The Gaussian exponential function is written e-(x-)/20 = 0.01 EXP(-((x)^2)/(2*^2)) (a) For = 10 and = 1, compute values of y for the range 4 x 16. (b) Repeat the calculation for = 2. (c) Plot the results of (a) and (b) on one graph. For = 2, label the regions that contain 68.3% and 95.5% of all observations. How Would You Do It? 850.0 $0.0
