The effects of skewness on mean, range, and standard deviation are clearly demonstrated in the accompanying graphic. Additionally, if you understand how mean, range, and standard deviation are calculated, the differences in the mean, range, and standard deviation between a Normal distribution...

Which, of course, should simplify to... c = (2 + Sqrt[2])/4 d = (2 - Sqrt[2])/4

Were the correct answers: Mean of the sample median: 1/2 Variance of the sample median: 1/(12 + 8m) Thanks! Jim

Homework Statement I was asked to find the general solutions of the two following differential equations: Q1. y'''[x] + 2 y''[x] + 5 y'[x] = 0 Q2. y''[x] + 6 y'[x] + 9 y[x] = 0 Homework Equations See above. The Attempt at a Solution My answers to both problems were of...
