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.
