Among fatal plane crashes that occurred during the past 50 years, 168 were due to pilot error, 67 were due to other human error, 488 were due to weather, 375 were due to mechanical problems, and 617 were due to sabotage. Construct the relative frequency distribution. What is the most serious threat to aviation safety, and can anything be done about it? Complete the relative frequency distribution below. Relative Frequency % % % Cause Pilot error Other human error Weather Mechanical problems Sabotage % (Round to one decimal place as needed.) What is the most serious threat to aviation safety, and can anything be done about it? A. Mechanical problems are the most serious threat to aviation safety. New planes could be better engineered. B.

Using the mean (= 89.7) and standard deviation (=9.9) as estimates of the population mean and standard deviation, a. Construct a diagram, using the Empirical Rule, to illustrate the percentagesof data values in each of the 8 sections that diagram includes.b. Between what two measurements will about 95% of the abdomencircumferences fall?
