You are a consumer journalist for a newspaper. You have received several letters and e-mails from readers who are concerned about the cost of their automobile insurance premiums. one of the readers wrote the following "I think, on the average a driver in our city pays a higher automobile insurance premium than drivers in other citites like ours in this state." Your editor asks you to investigate the costs of insurance premiums and write an article about it. You have gathered the data shown below (your city is City A). The data represent the automobile insurance premiums paid annually (in dollars) by a random sample of drivers in your city and three other cities of similar size in your state. (The prices of the premiums from the sample include comprehensive, collision, bodily injury, property damage, and uninsured motorist coverage.)
CITY A CITY B CITY C CITY D
2465 2514 2030 2345
1984 1600 1450 2152
2545 1545 2715 1570
1640 2716 2145 1850
1983 1987 1600 1450
2302 2200 1430 1745
2542 2005 1545 1590
1875 1945 1792 1800
1920 1380 1645 2575
2655 2400 1368 2016
1) Using the provided data, describe what you would do to investigate the statement about the price of automobile insurance premiums.
2) Identify the graph which would best display the data, and explain your choice.
3) Identify the statistical measures that would be used to analyze the data and calculate those measures, and explain your choice.
4) Share your conclusions and what you might tell your readers. Identify possible reasons why prices vary from city to city.
