85 to 100. 34% of the population has a score 100 to 115. This is done by subtracting and adding one standard deviation. 13% have scores 70 to 85 and 116 to 130. This is done by subtracting and adding 2 standard deviations. 2% have scores 55 to 69 and 131 to 145‚ which is done by doing the same math‚ but replacing it with 3 standard deviations. Yes.

Based on coefficients of variation‚ Investment 2 is still less risky than Investment 1. Since the two investments have different expected returns‚ using the coefficient of variation to assess risk is better than simply comparing standard deviations because the coefficient of variation considers the relative size of the expected returns of

Chase‚ Jacobs and Aquilano pose questions such as‚ “How many paint defects are there in the finish of a car? [and] Have we improved our painting process by installing a new sprayer?” These questions are meant to investigate and apply different techniques that we can use to improve the quality of life. Quality control not only applies to manufacturing techniques‚ it can also be applied to everyday life. This discussion will focus on a specific method of quality control called statistical process control

the targeted hold time of 110 seconds? Given that the daily average hold time was normally distributed with a mean of 99.67 and a standard deviation of 24.24‚ what fraction of days where the call center failed to meet the targeted hold time of 110 seconds would you expect? Answer) The targeted hold time x = 110 s The mean daily hold time μ = 99.67 s Standard Deviation σ = 24.24 s The fraction of days when hold time exceeded 110 s = P(x>110) =?

The client came to Quality Associates with a sample of 800 observations that they had collected during times when the manufacturing process was running smoothly. The sample of 800 yielded a sample standard deviation of 0.21. Quality Associates suggested that the company periodically take a sample of 30 to monitor their process on an ongoing basis to quickly learn if process was operating at a satisfactory level‚ and if not it could quickly be adjusted

A three-year study with 72 chronic cocaine users compared an antidepressant drug called desipramine against lithium (a standard drug to treat cocaine addiction)‚ and of course a placebo as well. The subjects were randomly assigned to receive each treatment. Here are the results: | | Cocaine Relapse? | Group | Treatment | Yes | No | 1 | Desipramine | 10 | 14
