- Based on Angel et al. (2003). A fertilizer companyis trying to determine the cheapest fertilizer mix thatprovides desired amounts of nutrients. The mix ismade by combining the following fertilizers: SSA,SPO, GUR, TSP, KCI, FERT, and SPF. The mix cannot contain both GUR and TSP. The percentage ofpotassium (K), sulfur (S), calcium (Ca), sodium (Na)and phosphorus (P) in each fertilizer is listed in the fileP06_88.xlsx. For example, a pound of SSA is 16% Kand 26% Na. The mix must contain at least 600 poundsof K, 550 pounds of S, 750 pounds of Ca, 900 poundsof Na, and 750 pounds of P. The mix cannot containboth GUR and TSP, because if both are present in themix, the affect of other fertilizers is nullified. The costper pound (in cents) of each fertilizer is listed in thesame file. Develop a linear integer model to find theminimum-cost fertilizer mixture that meets the statedchemical requirements.Company A receives large shipments of microprocessors from Company B. It must try to ensure the proportion of microprocessors that are defective is small. Suppose Company A decides to test ten microprocessors out of a shipment of thousands of these microprocessors.

If Company B's shipment contains 8% defective microprocessors, calculate the probability the entire shipment will be returned.

- The vintage Restaurant is located on Captiva Island, a resort community located near Fort Meyers, Florida. The restaurant, which is owned and operated by Karen Payne, has just completed its third year of operation. During this time, Karen sought to establish a reputation for the restaurant as a high-quality dining establishment that specializes in fresh seafood. The efforts made by Karen and her staff have proved successful, and her restaurant has become one of the best and fastest-growing restaurants on the island. Karen has just concluded that to plan better for the growth of the restaurant in the future, it is necessary to develop a system that will enable her to forecast food and beverage sales by the month for up to 1 year in advance. Karen has the following data available on the total food and beverage sales that were realized during the previous 3 years of operation. Food and Beverage Sales for the Vintage Restaurant ($1000s) Month First Year Second Year Third YearJanuary 242…The power takeoff driveline on tractors used in agriculture is a potentially serious hazard to operators of farm equipment. The driveline is covered by a shield in new tractors, but for a variety of reasons, the shield is often missing on older tractors. Two type of shields are the bolt-on and the flip- up. It was believed that the bolt-on shield was perceived as a nuisance by the operators and deliberately removed, but the flip-up shield is easily lifted for inspection and maintenance and may be left in place. In a study initiated by the National Safety Council of the U.S., a sample of older tractors with both types of shields was taken to see what proportion were removed. Of 183 tractors designed to have bolt-on shields, 35 had been removed. Of the 136 tractors with flip-up shields, 15 were removed. We wish to test the hypothesis H: Pb= PJ vs A: Pb ≠ f. Pl where Pb and Pꬵ are the proportion of tractors with the bolt-on and flip-up shields removed, respectively.

B) diversifying across insurance products. C) granting large numbers of independent risk policies. D) all of the aboveA university engineering department has introduced a new software package called SOLVIT. To save money, the university’s purchasing department has negotiated a bargain price for a 4 user license that allows only 4 students to use SOLVIT at any one time. It is estimated that thsi should allow 90% of students to use the package when they need it. The student's union has asked for more licenses to be bought since engineering students report having to queue excessively to use SOLVIT. As a result the computer Centre monitors the use of the software. Their findings show that on average 20 students are logged on at peak times and 4 of these want to use SOLVIT. Was the purchasing department estimate correct? Answer this by yes or no and show your proof why you choose yes or no.
