Researchers investigated how the size of a drinking glass affects how much soda people tend to pour themselves. People were randomly given either a 17 oz or a 25 oz glass, and were invited to pour as much soda as they liked. Did the glass size change the selected portion size?

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.

A single-server queue has random arrivals at a rate of 30 an hourand random service times at a rate of 40 an hour. If it costs £20 for each hour a customer spends in thesystem and £40 for each hour of service time, how much does the queue cost?
A regional package delivery company is considering changing from full-size vans to minivans. The company sampled 3 minivans from each of three manufacturers. Each minivan was driven for 5,000 miles, and the operating cost per mile was computed. The operating costs, in cents per mile, for the 9 minivans are provided in the table below: Manufacturer 1 Manufacturer 2 Manufacturer 3 15 11 14 14 13 16 13 12 15 Compute SST, SSE, and SS total and complete the ANOVA table.

An orange grower wishes to compute the average yield from her orchard. The orchard contains three varieties of trees: 52% of her trees are of variety A, 23% of variety B, and 25% of variety C. The orange grower takes a survey by sampling a certain number of trees of each variety. suppose that in her survey, she found that each tree of variety A averages 120 oranges, each tree of variety B averages 70 oranges, and each tree of variety C averages 90 oranges. Estimate the average yield per tree of her orchard. Round to the nearest whole number.
