Todd's Direct, a major TV sales chain headquartered in New Orleans, is about to open its first outlet in Mobile, Alabama,and wants to select a site that will place the new outlet in the center of Mobile's population base. Todd examines theseven census tracts in Mobile, plots the coordinates of the center of each from a map, and looks up the population basein each to use as a weighting. The information gathered appears in the following table.CensusTractPopulation in CensusTractX, Y MapCoordinates1012,100(26,44)1025,200(25,24)10310,500(57,42)1047,200(52,18)10510,400(80,48)10618,000(68,22)10714,000(84,22) a) The center-of-gravity coordinates for the location of the proposed outlet in Mobile, Alabama should be:X =(round your response to two decimal places).y =(round your response to two decimal places).b) Census tracts 103 and 105 are each projected to grow by 20% in the next year.

Silky Industries is looking for a location for its second telephone remanufacturing facility. Two cities are under consideration. The two most important location factors are: Factor A “availability of resources” and Factor B “availability of customers.” However, the company is having great difficulty assigning relative weights to these factors. Location Factor Factor Weight Factor Scorefor Each City Blake Irmo A. Availability of resources 5 6 B. Availability of customers 10 7 Total 100 Assuming that the factor weights must sum to 100, what range of weights would make Blake the superior location?
Alternative locations for a new drinking water treatment plant are being evaluated using four attributes identified as A, B, C, and D with weightsof 0.4, 0.3, 0.2, and 0.1, respectively.

True False Which question should be posed in determining the accuracy of secondary data? A. What information was collected? B. What was the purpose of the study? C. Both a & b. D. Neither a nor b.
Consider you are an owner of one IT organization with 200 employees and you want to keep track of the location information of each employee. You know that none of the employees will go out from the city and the radius of the city is 50 km.

Also, show how your chosen location measurement is better than the other ones.
A steel company is considering the relocation of one of its manufacturing plants. The company’s executives have selected four areas that they believe are suitable locations. However, they want to determine if the average wages are significantly different in any of the locations, since this could have a major impact on the cost of production. A survey of hourly wages of similar workers in each of the four areas is performed with the following results. Do the data indicate a significant difference among the average hourly wages in the three areas? Hourly Wages ($) Area 1 Area 2 Area 3 10 20 15 12 25 16 8 12 22 13 18 13 9 14 15 24 15 15 13 20 19 13 22 15 Step 1 of 2: Find the value of the test statistic to test for a difference in the areas. Round your answer to two decimal places, if necessary. Step 2 of 2: Make the decision to reject or fail to reject the null hypothesis of equal average hourly wages in the three areas and state the conclusion in terms of…

Location Problem with Two Sites. Oliveira Office Supply has a large retail system consisting of twelve stores spread around the country, often in direct competition with Kilroy. However, managers at Oliveira have decided to use two national distribution centers. When Oliveira's stores are mapped on the same grid as Kilroy's, the store locations occur at the coordinates listed in the following table. As in the previous exercise, there are also data to indicate how many trips are made annually to each store:Coordinates TripsSite (k) xk yk nk 1 2 96 21 2 5 41 12 3 20 10 20 4 44 48 15 5 60 58 27 6 100 4 8 7 122 94 21 8 138 80 16 9 150 40 1010 170 18 1811 182 2 2512 190 56 14A)Find the optimal location for Oliveira's two distribution centers in this expanded version of the problem.b) What is the optimal value of the objective function?
