Statistics & Process Capability

A data set contains 16 measurements as follows: 1525; 1561; 1541; 1532; 1499; 1551; 1554; 1528; 1514; 1548; 1534; 1505; 1500; 1538; 1529; 1519 the calculated mean = 1530 and the calculated std deviation = 19 The USL and LSL are respectively 1560 and 1510 and I therefore derive a CpK = 0.526 I know how to derive the normal distribution curve by plotting the probability and/or z-score for problem.....and I know how to derive the process sigma from the calculated z-score. But what I do not know......and this is what the problem asks, is to explain the relationship between CpK and process sigma........for instance, why does a CpK of 1.33 equate to process sigma of 4???? And in ... click for more

Quantitative Model

1. Micromedia is having a 2 day seminar in Microsoft Excel. The project fee is $300 per student. The conference room, instructor, assistants and promotion cost $4800. Micromedia rents the computers for its seminars at a cost of $30 per computer per day. a. Develop a model for the total cost to put on the seminar. Let x represent the number of students enrolled. b. Develop a model for the total profit if x students enroll in the seminar. c. Micromedia forecasted 30 students for the seminar, How much profit will be earned if this is accurate? d. Compute a break even point? ---------------------------------------------------------------- 2. The lifetime in hours of a ce... click for more

Assume that the VM will turn over four times next year.

Assume that the VM will turn over four times next year. If the country wants a GDP of $22 billion at the end of next year, what will have to be the size of the money supply? What percentage increase in the MS will be necessary achieve the target GDP? GDP = 20 MS = 5 VM=4

Relevant Costing

Thanks Again for your great assistance ! I need help with the following assignment (See attachment). Please note that part one deals with Wal-Mart Co. again and part two is just a scenario for the Air Frisco Co. Please note that in part two I scratched out $480 . Its actually $280. I made a typo.
