To reduce costs, a project team has decided to purchase a new weaving loom. The team must decide between two looms: the Josef and the Jurgens. Both looms have comparable quality levels and the same capacity, but different costs. The team needs to analyze the costs for both looms over a seven-year study period, with an MARR (an interest rate) of 12% per year. Loom 1: The Josef will cost $41,000 now, have operating costs of $6,000 per year, and have a salvage value of $3,000. Loom 2: The Jurgens will cost $83,000 now, have annual operating costs of $1,000, and have a salvage value of $7,000. What is the net present worth of the cash flows for Loom 1? [loom1] What is the net present worth of the cash flows for Loom 2? [loom2] Which loom should the team select? [select]

A bakery is analyzing whether cookie diameter varies with baking temperature. An experiment was run, with (20) cookies baked at a “low” temperature and (20) cookies baked at a “high” temperature. Assume the variance in height is equal for both temperatures. Which statistical test should be used to determine whether the mean cookie height from the “low” temperature is the same as the mean cookie height from the “high” temperature?

To increase capacity, a project team must decide between two weaving looms. Both looms have comparable capacity and quality levels, but different costs. The team must evaluate the costs over a five-year study period, with an MARR (an interest rate) of 8% per year. Loom 1: The Josef Loom will cost $11,500 now, have operating costs of $500 per year, and have a salvage value of $1,500 after 5 years. Loom 2: The Jurgens Loom will cost $9,500 now, have operating costs of $1,000 per year, and have a salvage value of $2,500 after 5 years. What is the net present worth of the cash flows for Loom 1?

Two gear hobbing machines, are used to produce a part for automotive transmissions. Scrap costs for one critical dimension are excessive. To determine whether there is a difference in mean performance for the two machines, a Six Sigma project team ran a small experiment. The Minitab output for the statistical analysis is shown below. Using a significance level of α = 0.05, the team concludes that:

A team at a popular magazine was formed to increase subscription response rate to direct mail offers. The team has identified eight factors in the design and mailing of the offer that could potentially affect response rate. Which tool should the team use next in order to understand the cause & effect relationship between the eight factors and subscription response rate? [tool]
