Compute the Coefficient of Variation for the data set A below. State your result as a decimal value with two digits after the decimal point (e.g. 3.15). Data set A: 1, 2, 3, 4, 5, 6
A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation.

The data represent the time, in minutes, spent reading a political blog in a day. Construct a frequency distribution using 5 classes. In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency? Complete the table, starting with the lowest class limit. (Simplify your answers.)

A biologist exposed a certain type of bacteria to gamma radiation to see how long they would live. He gathered data on the survival time of a number of bacterial cells and organized the data into the histogram below. Use the histogram to construct a frequency table. (The relative frequencies should be in decimal form.) 60+ 50 40 30 10 440 282 Survival Time (in Seconds) 45 124 203 361 519 Survival Time of Bacteria upon Exposure to Gamma Radiation Frequency Survival Time (in Seconds) Relative Frequency 45-124 124-203 203-282 282-361 361-440 440-519 Frequency 20
Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plotted along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 N 2 3 4 5 6 7 Class Class Boundaries 8 9 1.3 10 11 14.7 9.0 16.7 4.1 14.9 4.4 2.7 32.3 10.9 9.0 9.0 1.6 18.4 1.0 2.4 2.4 18.0 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3.5 11.2 18.0 26.7 3.7 3 to 6 6 to 9 9 to 12 12 to < 15 15 to 18 18 to 21 21 to 24 24 to 27 0.2 6.1 13.5 27 to < 30 30 to 33 7.4 8.2 19.2 1 1 2 1 Frequency 10 5 1 4 1 X X 9.4 X 8.7 X 2.0 6.6 3.9 5.9 4.3 3.3 0.2…
