Data 1
Data 2
Several measurements were taken on a lot of shims. Data from these measurements is in the MECH3050.Uncertainty.xls file under the DATA-1 tab. More samples were then measured. The larger sample data is found in the DATA-2 tab in the above file on Canvas. The data is given in thousandths of an inch, or mils. Report all answers to the fourth decimal place. Homework should be typed, including equations. Your submission should include excel spreadsheets or matlab code. However, simply printing excel files or matlab code will not be accepted as your submission. I. Calculate the 95% confidence intervals for both data sets: 2. Calculate the following considering only the large data set: . The probability of a measurement being within 1 standard deviation of the mean . The probability of a measurement being between 67.1 and 70.0 mils. . The probability of a measurement being between 68.5 and 73.3 mils. The assignment should be laid out in the following order. Begin with the smaller data set, then repeat for the large data set. 1. Confidence Intervals: State whether normal distribution or student\'s t distribution was used and why . Calculate sample mean using sample calculation method . Calculate sample standard deviation using sample calculation method . List the appropriate z or t-statistic for each confidence interval . Calculate each confidence interval. Each interval should be shown as a sample calculation 2. Calculate all three probabilities using the method of your choice. Show all steps of each calculation as in a sample calculation. No credit will be given if no work is shown. Integration by calculator is not acceptable for this assignment. If you numerically integrate, include all code in your submission.
If you have decided to use shims as part of your application compatibility mitigation strategy (for certain classifications of applications), the next question is, which strategy should you employ for managing custom shim databases? The customers Microsoft consultants have worked with have tended to select one of two approaches to managing their custom shim databases: deploying fixes as part of the application package or managing a centralized custom shim database.
Regardless of the approach your organization chooses, here are general recommendations for improving the management of custom shim databases:
Deploying fixes as part of an application package
One strategy for deploying application fixes is to include the custom shim database—containing a single entry for the application the package is installing—directly into the installation package. During the early phases of compatibility testing, this can seem like the easiest approach. However, over time this approach can grow more complex.
Microsoft consultants recommend evaluating the following considerations prior to selecting this approach:
