Cycle time in manufacturing can be viewed as the total time it takes to complete a product from the beginning of the production process. The concept of cycle time varies according to the industry and product or service being offered. Suppose a boat manufacturing company wants to estimate the mean cycle time it takes to produce a 16-foot skiff. A random sample of such skiffs is taken, and the cycle times (in hours) are recorded for each skiff in the sample. The data are analyzed using Minitab and the results are shown below in hours. What is the point estimate for cycle time? How large was the sample size? What is the level of confidence and what is the confidence interval?
The length of time it takes to complete a college placement test is normally distributed with a mean of 39 minutes and a standard deviation of 6 minutes. How much time (to the nearest minute) is needed so that 90% of the test takers have time to finish.
The Triple Bottom Line can be viewed as a three-legged stool in that each element must be present or, if one or more elements are removed, then the entire structure collapses. To what extent do you agree with this approach? Why is it important that each element be present?
A linear transformation T: first reflects points through the x1 -axis and then reflects points through the x2- axis. Show that T can also be described as a linear transformation that rotates points about the origin. What is the angle of that rotation?
Beta coefficients and the capital asset pricing model Katherine Wilson is wondering how much risk she must undertake to generate an acceptable return on her portfolio. The risk-free return currently is 5%. The return on the overall stock market is 16%. Use the CAPM to calculate how high the beta...

Jimmy McGill is an experienced lawyer who has not incorporated his professional practice. He doesn’t trust accountants as he was married to two of them (not at the same time). He operates his practice out of a building, which he purchased several years ago for $725,000. Of this total, it is...
How much experience do supply-chain transportation managers have in their field? Suppose in an effort to estimate this, 41 supply-chain transportation managers are surveyed and asked how many years of managerial experience they have in transportation. Survey results (in years) are shown below. Use...
Use the information about each of the following samples to compute the confidence interval to estimate p.a. n = 44 and p = .51; compute a 90% confidence interval.b. n = 300 and p = .82; compute a 95% confidence interval.c. n = 1,150 and p = .48; compute a 90% confidence interval.d. n = 95 and p =...
