A baseball team's success in a season is usually measured by their number of wins. In order to win, the team has to have scored more points (runs) than their opponent in any given game. As such, number of runs is often a good proxy for the success of the team. The table below shows number of runs, home runs, and batting averages for a random sample of 10 teams in the 2014 Major League Baseball season.
Team | Runs | Home runs | Batting Average |
Baltimore | 705 | 211 | 0.256 |
Boston | 634 | 123 | 0.244 |
Cincinnati | 595 | 131 | 0.238 |
Cleveland | 669 | 142 | 0.253 |
Detroit | 757 | 155 | 0.277 |
Houston | 629 | 163 | 0.242 |
Minnesota | 715 | 128 | 0.254 |
NY Yankees | 633 | 147 | 0.245 |
Pittsburg | 682 | 156 | 0.259 |
San Francisco | 665 | 132 | 0.255 |
1. Make a scatterplot of Runs vs. Home runs. Be sure to clearly label the graph.
2. Make a scatterplot of Runs vs. Batting Average. Be sure to clearly label the graph.
3.Are home runs or batting averages more strongly associated with number of runs? Explain your reasoning using complete sentences and proper grammar.

The Cereal FACTS report from Exercise 2.3 also provides information on sugar content of cereals. We have selected a random sample of 20 cereals from the data provided in this report. Shown below are the sugar contents (percentage of sugar per gram of cereal) for these cereals.
Brand | Sugar % | Brand | Sugar % |
Rice Krispies Gluten Free | 3% | Corn Pops | 31% |
Rice Krispies | 12% | Cheerios Honey Nut | 32% |
Dora the Explorer | 22% | Reese's Puff | 34% |
Frosted Flakes Red. Sugar | 27% | Pebbles Fruity | 37% |
Clifford Crunch | 27% | Pebbles Cocoa | 37% |

Cinnamon Toast Crunch | 30% | Pebbles Marshmallow | 36% |
Trix | 31% | Frosted Rice Krispies | 40% |
Honey Comb | 31% | Apple Jacks | 43% |
1. Make a stem and leaf plot of the distribution of sugar content of these cereals. You may make the graph by hand or using any technology you like. Be sure to fully and clearly label the plot.
2.Make a dot plot of the distribution of sugar content of these cereals. You may make the graph by hand or using any technology you like. Be sure to fully and clearly label the plot
3. Make a frequency table of the distribution of sugar content of these cereals. The first lower class limit is 0, with a class width of 5.
4.Using the frequency table from the previous question, make a frequency histogram of the distribution of sugar content of these cereals.
5.Make a relative frequency table of the distribution of the sugar content of these cereals. The first lower class limit is 0 and the class width is 5.
6.Using the relative frequency table from the previous question, make a relative frequency histogram of the distribution of sugar content of these cereals.
7.What percent of cereals contain more than 30% sugar?
