(a) Alter Equation (11) so that it determines the plane that passes through the origin and is parallel to the plane that passes through three specified noncollinear points. (b) Find the two planes described in part (a) corresponding to the triplets of points in Exercises 4(a) and 4(b).

● Population Variance ○ If N is the number of values in a population with mean mu, and xi represents each individual in the population, the the population variance is found by: ○ σ 2 = sumN i=1 (xi − µ) 2 N ○ and the population standard deviation is the square root, σ = √ σ 2. ○ Most of the time we are working with a sample...
