As manager of a pizza shop, you are responsible for placing the food orders. You currently have enough anchovies for 8 pizzas. You expect to have orders for 60 pizzas tonight.
 
  If 8 of all pizzas are ordered with anchovies, what is the probability that you run out of anchovies before the evening is over? Use the normal approximation for the binomial.

Question 2

Determine the value of the sample median.
 
  What will be an ideal response?

Answer to Question 1

P = 0.08, n = 60,  = E(X) = 4.8, 2 = Var(X) = nP(1 - P) = 4.416, = 2.1
P(X > 8 ) = P(Z > 1.52 ) = 0.0643

Answer to Question 2

The sample size n = 11 is odd, so there will be a middle value. Sorting the data values from smallest to largest produce the following; 4.4, 16.4, 22.2, 30.0, 33.1, 36.6, 40.4, 66.7, 73.7, 81.5, and 109.9. The sixth value, 36.6 is the middle, or median, value.
