A quality analyst wants to construct a sample mean chart for controlling a packaging process. He knows from past experience that whenever this process is in control, package weight is normally distributed with a mean of 20 ounces and a standard deviation of two ounces. Each day last week, he randomly selected four packages and weighed each:

Day WEIGHT (ounces)

Monday 23 22 23 24

Tuesday 23 21 19 21

Wednesday 20 19 20 21

Thursday 18 19 20 19

Friday 18 20 22 20

If he uses upper and lower control limits of 22 and 18 ounces, on what day(s), if any, does this process appear to be out of control?

You are an employee of an u. s. firm that produces personal computers in thailand and then exports them to the united states and other countries for sale. the personal computers were originally produced in thailand to take advantage of relatively low labor costs and a skilled workforce. other possible locations considered at that time were malaysia and hong kong. the u. s. government decides to impose punitive 100% ad valorem tariffs on imports of computers from thailand to punish the country for administrative trade barriers that restrict u. s. exports to thailand. how do you think your firm should respond? what does this tell you about the use of targeted trade barriers?

Dahlia enterprises needs someone to supply it with 127,000 cartons of machine screws per year to support its manufacturing needs over the next five years, and you’ve decided to bid on the contract. it will cost you $940,000 to install the equipment necessary to start production; you’ll depreciate this cost straight-line to zero over the project’s life. you estimate that in five years, this equipment can be salvaged for $77,000. your fixed production costs will be $332,000 per year, and your variable production costs should be $11.00 per carton. you also need an initial investment in net working capital of $82,000. if your tax rate is 30 percent and your required return is 11 percent on your investment, what bid price should you submit? (do not round intermediate calculations and round your final answer to 2 decimal places. (e. g., 32.16))
