let x be a binomial random variable with n=15 and p=0.5. Using the exact binomial calculation and the normal approximation with the continuity correction, Find P(x>6) A. .6964, .745 B. .1527, .3036 C. .6964, .6972 D. .3036, .3036 E. .849, .745 I think you have to find x first right by doing the square root of np(1-p) and then do you do like normalcdf(15, E99, .5, x)?
