Question : What two-hour time frame is best for Life Flight to take its helicopters out of service for scheduled maintenance?

Hypothesis : It would be best for Life Flight to begin its routine maintenance between the hours of 0400 and 0600.

Assignment : Using the random sample attached (30 days of flight volume broken down into two hour intervals):

1. Define the methodology used.
2. Determine how the data is distributed.
3. Analyze against the normal distribution, i.e. evaluate the properties of the distribution using measures of central tendency, variation, and shape.
4. Describe all of the data/conclusions using descriptive statistics (mean, mode, median, standard deviation, etc.)
5. Perform an analysis using appropriate statistical ‘inferential’ methodologies.
6. Include appropriate graphs, plots, i.e. histograms, cumulative distribution, relative frequency, contingency tables, box-plots, etc.
7. Test results should include the formulas used with appropriate notation.
8. Provide recommendations and a conclusion that direct support the analysis.
9. Include confidence interval testing of at least 95%.
10. T-test. Z-test.
11. Test using the null and alternative hypothesis.
12. P-value.
13. ANOVA, (SST, SSA, SSW).
14. Regression analysis with appropriate graphs.
