Giapetto is thinking of buying a new cutting tool for $20 to make toy soldiers and a new clamping tool for $15 to make toy trains. If he does not buy a new tool, he can still make a toy using the older tool he already has. However, using an old cutting tool leads to 50% of the produced soldiers and using an old clamping tool leads to 20% of the produced trains to be defective. With a new tool, there is no defective production. Giapetto cannot sell any defective product. Weekly demands (must be met exactly without left- over inventory) and productions costs are as follows: 1. Soldiers 2. Trains Demand (units/week) Production cost ($/unit) 400 300 7 17 There are other details about the problem which will be added later. Giapetto started formulating a mathematical model considering only the above description and defined the following decision variables: • xi: Production quantity for type i toy, i = 1, 2 corresponding to soldiers and trains, respectively. Considering the above problem…
The developer of a new residential area has plans for houses, parks, a school, and a community centre, connected by roads and footpaths. Some of these areas need to be fenced off. The developer proposes to use "solar fences" using vertically mounted bidirectional solar panels, which generate electricity whichever side of the fence the sun is shining on. The electricity would be sold to local residents at 10% less than the cost of buying electricity from the local electric utility. This would decrease revenues for the local electric utility which is owned by the city. The city council decides to give planning permission for solar fences if > 50% of residents are in favour. It selects 34 residents at random and finds that 23 of them support the installation of these solar fences. Complete parts (a) through (c). a) Check whether the city should give planning permission at the 10% significance level using a hypothesis test. Let p be the proportion of people that support the installation of…
