Toward the middle of the harvesting season, peaches for canning come in three types, early, late, and extra late, depending on the expected date of ripening. During a certain week, the data to the right were recorded at a fruit delivery station. Complete parts (a) through (d) below. 40 trucks went out carrying early peaches; 71 carried late peaches; 52 carried extra late peaches; 26 carried early and late; 32 carried late and extra late; 11 carried early and extra late; 6 carried all three; 5 carried only figs (no peaches at all). a) How many trucks carried only late variety peaches? trucks (Type a whole number.)

Floyd Distributors, Inc., provides a variety of auto parts to small local garages. Floyd purchases parts from manufacturers according to the EOQ model and then ships the parts from a regional warehouse direct to its customers. For a particular type of muffler, Floyd's EOQ analysis recommends orders with Q* = 20 to satisfy an annual demand of 180 mufflers. Floyd's has 250 working days per year, and the lead time averages 15 days.Note: Use Appendix B to identify the areas for the standard normal distribution. What is the reorder point if Floyd assumes a constant demand rate? If required, round your answer up to the nearest whole number. r = fill in the blank 1 Suppose that an analysis of Floyd's muffler demand shows that the lead-time demand follows a normal probability distribution with µ = 12 and σ = 2.2. If Floyd's management can tolerate one stock-out per year, what is the revised reorder point? If required, round your answer up to the nearest whole number. r = fill in the blank…

ABC Company has decided to use 20 test markets to examine the sensitivity of demand for its new product, Hand Sanitizer, to various prices, as shown in the following table. Each market had approximately the same level of business activity and population.

The production planning period for flat-screen moni-tors at Louisiana’s Roa Electronics, Inc., is 4 months. Cost data are as follows:Regular-time cost per monitor $ 70Overtime cost per monitor $110Subcontract cost per monitor $120Carrying cost per monitor per month $ 4 For each of the next 4 months, capacity and demand for flat-screen monitors are as follows: PERIOD MONTH 1 MONTH 2 MONTH 3 a MONTH 4Demand 2,000 2,500 1,500 2,100CapacityRegular time 1,500 1,600 750 1,600Overtime 400 400 200 400Subcontract 600 600 600 600aFactory closes for 2 weeks of vacation.CEO Mohan Roa expects to enter the planning period with 500monitors in stock. Back ordering is not permitted (meaning, forexample, that monitors produced in the second month cannot beused to cover first month’s demand). Develop a production planthat minimizes costs using the transportation method.
The product design group of Iyengar Electric Supplies,Inc., has determined that it needs to design a new series of switches.It must decide on one of three design strategies. The market forecastis for 200,000 units. The better and more sophisticated the designstrategy and the more time spent on value engineering, the less willbe the variable cost. The chief of engineering design, Dr. W. L.Berry, has decided that the following costs are a good estimate of theinitial and variable costs connected with each of the three strategies:a) Low-tech: A low-technology, low-cost process consisting ofhiring several new junior engineers. This option has a fixedcost of $45,000 and variable-cost probabilities of .3 for $.55each, .4 for $.50, and .3 for $.45.b) Subcontract: A medium-cost approach using a good outsidedesign staff. This approach would have a fixed cost of $65,000and variable-cost probabilities of .7 of $.45, .2 of $.40, and .1 of $.35.c) High-tech: A high-technology approach using the very…
Suppose the true inverse demand relation for good X is Qdx = a + bPx + cM + e , and you estimated the parameters to be â = 22, b ˆ = −1.8, σâ = 2.5 , and σb ˆ = 0.7 . Find the approximate 95 percent confidence interval for the true values of a and b.
In the packaging department of a large aircraft parts distributor, a fairly reliable estimate ofpackaging and processing costs can be determined by knowing the weight of an order. Thus, theweight is a cost driver that accounts for a sizable fraction of the packaging and processing costsat this company. Data for the past 10 orders are given as follows:
