Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
