Question

applying the concepts 1 - 2 fatal transportation injuries read the following information about the number of fatal accidents for the transportation industry in for a specific year, and answer each question. industry number of fatalities highway accidents 968 railway accidents 44 water vehicle accidents 52 aircraft accidents 151 source: bureau of labor statistics 1. name the variables under study. 2. categorize each variable as quantitative or qualitative. 3. categorize each quantitative variable as discrete or continuous. 4. identify the level of measurement for each variable. 5. the railroad had the fewest fatalities for the specific year. does that mean railroads have fewer accidents than the other industries? 6. what factors other than safety influence a person’s choice of transportation? 7. from the information given, comment on the relationship between the variables. exercises 1 - 2 1. explain the difference between qualitative variables and quantitative variables. 2. explain the difference between discrete and continuous variables. 3. why are continuous variables rounded when they are used in statistical studies? 4. name and define the four types of measurement levels used in statistics. for exercises 5 - 10, determine whether the data are qualitative or quantitative. 5. sizes of soft drinks sold by a fast - food restaurant (small, medium, and large) 6. pizza sizes (small, medium, and large) 7. cholesterol counts for individuals 8. microwave wattage for exercises 11 - 16, determine whether the data are discrete or continuous. 11. number of phone calls received by a 911 call center each day 12. systolic blood pressure readings 13. weights of the suitcases of airline passengers on a specific flight 14. votes received by mayoral candidates in a city election 15. number of students in the mathematics classes during the fall semester at your school for a particular school year 16. temperatures at a seashore resort for exercises 17 - 22, give the boundaries of each value. 17. 24 feet 18. 6.3 millimeters 19. 143 miles 20. 19.63 tons 21. 200.7 miles 22. 19 quarts for exercises 23 - 30, classify each as nominal - level, ordinal - level, interval - level, or ratio - level measurement. 23. telephone numbers 24. leap years: ... 2016, 2020, 2024, ... 25. distances communication satellites in orbit are from earth 26. scores on a statistical final exam 27. rating of cooked ribs at a rib cook - off 28. blood types—o, a, b, ab 29. online spending in dollars 30. horsepower of automobile engines

Explanation:

Step1: Identify variables

The variables are "Industry" and "Number of fatalities".

Step2: Categorize variable types

"Industry" is qualitative as it represents categories (Highway, Railway, etc.). "Number of fatalities" is quantitative as it represents counts.

Step3: Categorize quantitative variable type

"Number of fatalities" is discrete since it is a count of whole - numbers.

Step4: Identify measurement levels

"Industry" is nominal (categories with no order). "Number of fatalities" is ratio (has a true zero and ratios are meaningful).

Step5: Answer question 5

Just because railroads had the fewest fatalities in a specific year doesn't mean they have fewer accidents overall. There could be factors like fewer trips, different exposure levels, etc. So the answer is no.

Step6: Answer question 6

Factors other than safety like convenience (e.g., proximity of stations, door - to - door service), cost (ticket price, fuel cost for personal vehicles), speed, and availability influence a person's choice of transportation.

Step7: Answer question 7

There seems to be a relationship between the type of industry (transportation mode) and the number of fatalities. High - volume industries like highways may have more fatalities, while those with lower usage like water vehicles may have fewer.

Answer:

1. Variables: Industry, Number of fatalities
2. Industry: Qualitative; Number of fatalities: Quantitative
3. Number of fatalities: Discrete
4. Industry: Nominal; Number of fatalities: Ratio
5. No
6. Convenience, cost, speed, availability
7. Relationship between transportation mode and number of fatalities exists; high - volume modes may have more fatalities
