13. The proportion of pepperoni pizza orders on a randomly selected day at a local pizza shop is approximately normal with mean 0.25 and standard deviation 0.02. Let X = the proportion of pepperoni pizza orders on a randomly selected day. (a) Carefully sketch a normal curve for this situation. Be sure to label the mean and one, two, and three standard deviations on each side of the mean. Use the 68-95-99.7 rule to approximate: (b) P(X > 0.29) (c) The probability that the proportion of pepperoni pizza orders is between 0.21 and 0.27 Use Table A to answer the following: (d) What is the probability that the proportion of pepperoni pizza orders is between 0.24 and 0.28? (e) What is the probability that the proportion of pepperoni pizza orders is greater than 0.30
