The cumulative distribution function : R R of the standard normal N (0, 1) can be written as Enter inf for co. A = B = where B (z) is a function of z and C (x) is a function of x. Write down the integration limits A, B (z), as well as the function C (x) in the integrand. C = B(z) 1 (z) = -S) .ec(x) dx
