Math worksheet- due in 5 hours.

Drug X was administered after surgery to half of the participating patients in order

to determine whether the recovery time could be improved.

Amount of Hours during Recovery:

1) Men with Drug X: 32, 33.75, 30.25, 26.5, 28.25, 27, 31.5, 28, and 27.75

2) Men without Drug X: 38, 39.5, 40.25, 36.25, 37, 35.75, 34.25, 38.25, and 31.5

3) Women with Drug X: 34.5, 32.75, 35.25, 30, 30.5, and 31.75

4) Women without Drug X: 35.75, 38.5, 33.75, 33, 34.5, and 32

Classes: (25.6 – 28.5), (28.6 – 32.6), (32.6 – 36.5), and (36.6 – 41.5)

Statistical Graphs Worksheet

Read the following study description.

Complete the following six activities, referring to the study description. Include all necessary

graphs and charts with your answers.

1. Using the four classes, create a frequency table, relative frequency table, and cumulative

frequency table for each of the four groups listed above.

2. Create a histogram and a relative frequency histogram for each of the groups.

3. Identify the shape of the distribution for each of the groups.

4. Identify which of the relative frequency histograms in part B would also be considered a

Pareto chart. Explain your answer.

5. Create an ogive for each of the groups.

6. Create a pie-chart for the total number of people in the study and the average recovery time for

each group.
