The variation (6 x standard deviation) of a gauge repeatability and reproducibility study is 0.26. If the tolerance is +/- 0.15, then what is the percent of tolerance? Use letters in alphabetical order to select options A
Homework Answers
The percentage of tolerance=
In this problem, reproducibility = 0.26
Total tolerance range = 0.30
Therefore tolerance percent = 86.67
Please give a thumbs up if you like my answer.If you have further doubts then please let me know in the comment section.Thanks.

The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units.

The coefficient of variation is a better measure of stand-alone risk than standard deviation because it is a standardized measure of risk per unit; it is calculated as the -Select- divided by the expected return. The coefficient of variation shows the risk per unit of return, so it provides a more meaningful risk measure when the expected returns on two alternatives are not -Select- .. The Sharpe ratio compares the asset's realized excess return to its -Select- over a...

Security X has an expected return of 15% and a standard deviation of 35%, and is to be continued in a portfolio with Security Y. The correlation between both assets is 0.75. An investor plans to invest $3000 in Security X and $7000 in Security Y. (a) What will be the expected return om the portfolio? (b) If the investor has a risk tolerance of only 25% or less, will this be achieved? Show with calculations accurate to two decimal...
