I have this question that I need to answer for my Black Belt study. Im confident that question related to normality testing but am confused as to how it can be assessed given the lack of data in question needed to answer it??? Any ideas???
Background.Two underwriters, Adam and Joan, process a total of 200 Mortgage Insurance deals over a 1 week period. The deals are essentially the same apart from size (large or small). A large deal is more complex and takes longer to process. A Six Sigma team has been assigned to analyse the data, before they can – YOU must validate that the data collected is fair and representative.
Results.
Adam. Large deals = 21; Small deals = 94
Joan. Large deals = 27; Small deals = 58
Questions.
1. What type of data are you dealing with here ?
2. What type of statistical test do you propose to use ?
3. State your Hypothesis test in terms of Ho and Ha.
4. Using Minitab, what results do you get (for the p-value and the ) ?
5. Show me how you would calculate, by hand, this test result (not the p-value, the test result).
6. What does that tell you about the data, ie: do you reject Ha and accept Ho; or reject Ho and accept Ha ?
