Suppose X ~ B(b,0.c)(Use the value B(84,0.40)).

i) For this distribution, is the normal approximation reasonable? Your answer must make reference to skewness.

ii) If you take a sample of size 120, what's the approximate probability that the proportion of successes will be larger than 0.65? (Answer this regardless of your answer to i.)
