In the code numdif, change x to x = 3/2 and then compare the results to both f (3/2) = .036489974 and f (3/2) = .9348022005. Compute the percentile points of the normal distribution for = .10, .05,...

In the code numdif, change x to x = 3/2 and then compare the results to both f (3/2) = .036489974 and f (3/2) = .9348022005.

Compute the percentile points of the normal distribution for α = .10, .05, .01 by finding the roots of the equation (x) − α = 0.
