About 10% of people in the United States have type B blood. Suppose we select a ran- dom sample of 120 U.S. residents, and let Y = the number of residents in the sample who have type B blood. (a) Show that the probability distribution of Y is approximately normal. np = 12 and n(1-p) = 108 The probability distribution of Y is approximately normal because np and n(1-p) are both at least 10. (b) Calculate the mean and standard deviation of the appropriate normal distribution. Mean = 12 residents (Do not round your answer.) Standard Deviation = 3.29 residents (Round your answer to 2 decimal places.) (c) Use this normal distribution to calculate the probability that 16 or more individuals in the sample have type B blood. I Probability = Round to 4 decimal places. Leave your answer in decimal form.

2) (20 points) The purchase price of a brand new 3-D printer is $25,000. First year's O&M expenses are expected to be $2,000 and they are expected to increase by $200 per year from the second year onwards. Because of the rapid advances in the 3-D printing technology, the printer is expected to have negligible salvage value at the end of its useful life of 5 years. MARR is 10% per year compounded annually. a) (8 points) What is the capital recovery (CR) cost for this 3-D printer? b) (12 points) Determine the equal uniform annual cost of owning and operating this 3-D printer.
