In alphabetical order, the six most common last names in the United States are Brown, Johnson, Jones, Miller, Smith, and Williams (The World Almanac, 2012). Assume that a sample of 50 individuals with one of these last names provided the following data. The data set is available in file named 2012Names.xlsx in chapter 2.   Use Excel to summarize the data by constructing the following: a. Frequency and percent frequency distributions. b. A bar chart. c. A pie chart.

Among fatal plane crashes that occurred during the past 70 years, 684 were due to pilot error, 97 were due to other human error, 679 were due to weather, 240 were due to mechanical problems, and 218 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. Cause Relative Frequency Pilot error % Other human error % Weather % Mechanical problems % Sabotage % (Round to one decimal place as needed.)

Among fatal plane crashes that occurred during the past 65 years, 517 were due to pilot error, 98 were due to other human error, 673 were due to weather, 60 were due to mechanical problems, and 139 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 Pilot error % 11 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? Cause % G O A. Pilot error is the most serious threat to aviation safety. Pilots could be better trained. O B. Sabotage is the most serious threat to aviation safety. Airport security could be increased. O C. Mechanical problems are the most serious threat to aviation safety. New planes could be better engineered. O D. Weather is the most serious threat to aviation…
