c) Considering the network diagram below, the management of MTN needs to determine under which roads telephone lines should be installed to connect all stations with a minimum total length of line. With your knowlege in network analysis, how can you aid management in drawing the minimum spanning tree and to find the minimum total length of

Suppose that in solving a TSP you use the nearest-neighboralgorithm and find a nearest-neighbor tour with a total costof $13,500. Suppose that you later find out that the cost ofan optimal tour is $12,000. What was the relative error ofyour nearest-neighbor tour? Express your answer as a percentage,rounded to the nearest tenth of a percent.

Otitis media, or middle ear infection, is initially treated with an antibiotic. Researchers have compared two antibiotics, A and B, for their cost effectiveness. A is inexpensive, safe, and effective. B is also safe. However, it is considerably more expensive and it is generally more effective. Use the tree diagram to the right (where the costs are estimated as the total cost of medication, office visit, ear check, and hours of lost work) to answer the following. a. Find the expected cost of using each antibiotic to treat a middle ear infection. b. To minimize the total expected cost, which antibiotic should be chosen? a. The expected cost of using antibiotic A is S (Round to the nearest cent as needed.)

Determine the minimum distance required to get from farm 1 to farm 6. The farmers decided to install cable for television and Internet connections. Determine the minimum amount of cable required to connect all 6 farms.

A new park is being developed with five campgrounds. Trails connecting each campground need to be constructed at the least cost. The cost is the same for each mile of trail in the entire park. Use the following table to determine the spanning tree with least cost. How many miles of trails is the least cost?

See Picture.  Thank you for your help. Questions 1) Construct comparative boxplots for the thicknesses of new wafers and recycled wafers. You have the option to create them by pencil and paper, or by Microsoft Excel spreadsheet (submit it with assignment, properly labeled), or by a graphing calculator (take pictures and submit them with assignment, properly labeled).  A) Label each boxplot completely.  B) Give the 5-Number Summary, mean, and standard deviation for both the new wafers and recycled wafers. You have the option to calculate them by pencil and paper (show all work), or by Microsoft Excel spreadsheet (submit with assignment, properly labeled), or by a graphing calculator (take pictures and submit with assignment, properly labeled).
