Answer the following questions. Show all work (where appropriate) if you want any partial credit. 1. One of the variables of a study was the number of days a patient was in a coma after suffering a closed head injury. The sample data for the 17 patients is the following. class width 4.3 2.0 11.9 6.3 7.4 8.5 9.8 10.4 11.2 11.3 11.8 12.4 12.5 13.1 13.3 14.0 16.8 19.2 a. Construct a relative frequency table for this data, using 4 classes and class intervals of the following form: 2.0 to 6.3, 6.4 to 10.7, etc. (4 points) Frequency 2 Days in Coma 2.0 to 6.3 6.4 to 10.7 4 Relative Frequency (Fru/n) 2/1 = 0.118 4/17= 0.235 bar graph for quantitative variables b. Construct a frequency histogram for the number of days in a coma. (4 points) 2. A pharmaceutical company is interested in the average change in blood pressure of patients who take a new drug to treat diabetes. Twenty-two patients are randomly selected from the population of all patients who take this drug. The 22 test patients have the following blood pressure increases: 4.0 1.8 a. 3.6 2.8 2.9 (5.2) 2.4 0.2 1.3 11.5) 1.2 0.5 1.3 2.7 Find the 5-Number Summary for this data. (5 points) 4.7 -0.8 -3.3 3.5 5.8 4.3 2.0 8.2 b. Identify any outliers that exist for this data set. (4 points) c. Calculate the sample mean for this data. (4 points) sample mean = d. Calculate the sample standard deviation for this data. (4 points) sample standard divation: Answer the following questions. Show all work (where appropriate) if you want any partial credit. 1.
