1. For the Park City basketball team, scores for the last 30 games were as follows (smallest to largest): 32; 32; 33; 34; 38; 40; 42; 42; 43; 44; 46; 47; 47; 48; 48; 48; 49; 50; 50; 51; 52; 52; 52; 53; 54; 56; 57; 57; 60; 61. Construct a stem plot for the data.
2. The population in Park City is made up of children, working-age adults, and retirees. The frequency table below shows the three age groups, the number of people in the town from each age group, and the proportion (%) of people in each age group. Construct a bar graph showing the proportions.
| Age groups | Number of people | Proportion of population |
| Children | 67,059 | 19% |
| Working-age adults | 152,198 | 43% |
| Retirees | 131,662 | 38% |
3.The following data represent the number of employees at various restaurants in New York City. 22; 35; 15; 26; 40; 28; 18; 20; 25; 34; 39; 42; 24; 22; 19; 27; 22; 34; 40; 20; 38; and 28. Using this data, create a frequency table. Beginning with a lower class limit of 10 and a class width of 10. Also include the relative frequency.
| Number of Employees | Frequency | Relative Frequency |
4. Construct a histogram using class boundaries and frequency.
5. Construct a histogram using class midpoints and relative frequency.
