      Approximating Binomial Distribution Probabilities. Recall the probability formula for Binomial Random Variables: P(X=k)= *As n gets large this formula becomes difficult to compute because of the factorials involved. *However, the normal distribution can be used to approximate probabilities for a binomial random variable when this situation occurs.

      Step 1: The probability of drawing the short straw randomly = 1 / 5 = .2 . H0 = p = .2 H1 = p > .2 . Step 2: Binomial distribution (since Anton draws first, he either gets the short straw or doesn’t so there are two possible outcomes) Step 3: alpha = .05, this is a directional or one-tailed test
