Statistical Graphs Worksheet Read the following study description. 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) 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. Statistical Sampling Worksheet Read the following study description. A study is designed to determine whether the recovery rate of a patient after surgery could be improved by providing the patients with a newly developed drug (Drug X). The 30 patients at a local hospital who agreed to participate in the study were divided into two groups based on gender (18 men and 12 women). Half of the men and half of the women (selected by random) received Drug X immediately after the surgery, while the others did not. The doctor administering the drug was the only person who knew which patients received Drug X. The patients in the study and the nurses working with the patients on the hospital floor were not told who received Drug X. The recovery rate for each patient was determined by the number of hours after surgery it took before the patient was able to walk around the hospital floor. The average recovery rates for men and women who took Drug X and who did not were compared within their gender groups as well as with each other. Complete the following five activities, referring to the study description. 1. Identify all the quantitative and qualitative variables within the study. For each variable, identify the level of measure. 2. Identify the sampling technique used in the study. Justify your response. 3. Explain how each of the following words are related to this study: a. randomized block design, b. double-blind experiment, c. placebo effect d. control group e. treatment group f. replication 4. Identify a lurking variable from the study. Explain why the variable you selected may have an impact on the study's results. 5. Describe the aspects of the study that are statistically sound and the aspects that are not statistically sound
