In the data table​ below, the​ x-values are the weights​ (in pounds) of cars and the​ y-values are the corresponding highway fuel consumption amounts​ (in mi/gal).

Given the context of the car measurement​ data, what issue can be addressed by conducting a statistical analysis of the​ values?

Is there a relationship or an association between the weight of a car and its fuel consumption​ amount?

2

An editorial criticized a chart caption that described a dental floss as one that "reduces the chance of plaque on teeth by over 400 percent."

What is wrong with this​ statement?

A reduction of 100% would eliminate all plaque, so it is not possible to reduce it by more than 100%.

3

The​ x-values in the table to the right are the nicotine amounts​ (in mg) in different 100 mm​ filtered, non-"light" menthol cigarettes. The​ y-values are the nicotine amounts​ (in mg) in different​ king-size nonfiltered,​ nonmenthol, and​ non-"light" cigarettes.

If suitable methods of statistics are​ used, it can be concluded that the average​ (mean) nicotine amount of the 100 mm​ filtered, non-"light" menthol cigarettes is less than the average​ (mean) nicotine amount of the​ king-size nonfiltered,​ nonmenthol, and​ non-"light" cigarettes.

Can it be concluded that the first type of cigarette is​ safe? Why or why​ not?

Since the first type of cigarette contains less nicotine than the second type of​ cigarette, the first type is safer.​ However, it cannot be concluded that it is safe.
