Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction. Use the data in the table above to make a stem-and-leaf display for milligrams of tar per cigarette smoked. (Enter NONE in any unused answer blanks.) Are there any outliers? A. Yes, 1.0 may be an outlier. B. No, there are no outliers.     C. Yes, 29.8 may be an outlier.

1. The two plots have similar distrubutions. Are the distrubutions skewed left, approximtly symmetric, or skewed right? 2. Which is greater, the mean or the median, within each plot? Why does this make snese, gicen the type of distrubution you identified in the first part? 3. The population has drastically declined over recent years. Does the data show a difference in bee prefrence towards high quality hives versus how quality hives? Usse statistical evidennce to support your response.
