1. Create a frequency distribution table, histogram and polygon for the data below. Then, describe the shape of the distribution: 5, 4, 2, 5, 4, 3, 4, 3, 4, 5, 4, 3, 5, 4, 1 2. The following scores are the ages for a random sample of n = 30 drivers who were issued speeding tickets in New York during 2008. Determine the best interval width and place the scores in a grouped frequency distribution table. From looking at your table, does it appear that tickets are issued equally across age groups? 17, 30, 45, 20, 39, 53, 28, 19, 24, 21, 34, 38, 22, 29, 64, 22, 44, 36, 16, 56, 20, 23, 58, 32, 25, 28, 22, 51, 26, 43 3. The numbers below are the number of aggressive acts for each preschool child over a week in a class of 25 students. a. construct a frequency distribution, including the real limits, size, and midpoints of the class intervals. For such a small distribution only five or so intervals are necessary. b. compose a relative frequency, cumulative frequency, and cumulative relative frequency distribution for these data. c. construct polygons and histograms for the frequency and relative frequency distributions and a polygon for the two cumulative distributions. 36, 28, 47, 40, 44, 44, 39, 33, 33, 32, 47, 34, 38, 27, 40, 37, 41, 42, 38, 48, 43, 35, 37, 37, 26 4. For the following scores, construct a grouped frequency distribution table using an interval width of 10 points. Based on the table, what is the shape of the distribution? 30, 23, 58, 28, 35, 67, 74, 59, 27, 42, 46, 35, 51, 33, 18, 33, 25, 38, 48, 36, 31, 39, 63, 40 5. If a set of exam scores forms a negatively skewed distribution what does it suggest about the scores that the students received on the exam? Obillo1991@gmail.com Obillo1991@gmail.com
