The report must include:
– Introduction on the statistic analysis.
– Aims and Objectives of studying this case in statistical way
-Problem statement
-Background of the generally on Aviation Accidents Mainly on period of 1908 to 1943 years, study in statistic analysis.
-Figures and results graphical presentation Must be DONE IN EXECL or SPSS programs and EXPLAIN EACH GRAPH STATISTICALY
: Statistical Analysis Requirements
1. Use the data tables provided to generate the plot histogram for Type of aircraft and Fatality (from the Data in the Excel). What does the histogram indicate?
2.Calculate descriptive statistics (mean, standard deviation, variance, range, median, quartiles, IQR) for each subset of data in above.
3.GeneratetheProbabilityDistributionPlotforeachtableofdata.
4.Calculate the Confidence Interval estimate of population mean for each of data
sub sets. Compare the CI for each consecutive pair of data subsets.
5.In order to prove independencies of each subset data, use Z-test, T-test and χ2
Chi-squares test for the variance. Comment on all subsets data tests.
6.Plot the mean of each subset data vs. the defect number and obtain the empirical relationship between these variables using Linear Regression Analysis. What
does the plot “relationship” indicate?
7.Perform Hypotheses Testing for all data subsets and comments on the results.
8. Results must be discussion and Conclusions
Note: The graphs must be add in the appendixes not in the contents itself
