A simple random sample of 40 college students was surveyed. The
number of participants in given age ranges were recorded in the
table below. Complete the table, computing the class midpoints,
relative frequencies, cumulative frequencies and the cumulative
relative frequencies for each class. Express answers as decimals
rounded to 2 decimal places. Then use the table to answer the
following questions.
| Ages | Class Midpoint | Frequency | Rel. Freq. | Cumulative Freq. | Cumulative Rel. Freq |
| 15-24 | 20 | ||||
| 25-34 | 16 | ||||
| 35-44 | 8 | ||||
| 45-54 | 4 | ||||
| 55-64 | 2 |
Draw a relative frequency histogram for the ages of the students in the sample. Label the axes appropriately, including the scale used and describe the shape of distribution ( uniform, skewed-left, skewed right, or bell shaped).
