Fill in the space. 1. A is a study in which data are obtained from every member of the population. 2. A quantitative data that can take on any value in a given interval and are usually measurements is called 3. Data at the is qualitative and can be arranged in a meaningful order, but calculations such as addition or division does not make sense. 4. Factors other than the treatment that can cause an effect on the subjects of an experiment is called 5. is the science of gathering, describing, and analyzing data or actual numerical descriptions of sample data. 6. is the difference between the lower limits or upper limits of two consecutive classes of a frequency distribution. 7. What is the class midpoint of the class 21-25? 8. Find the upper class boundary for the class 26-30. 9. The fraction or percentage of the data set that falls into a particular class is called and is given by the formula 10. A visual display of the frequency of each class of quantitative data that uses straight lines to connect points plotted above the class midpoints is called1. The following data represent the number exercises at the end of various sections in a traditional college algebra textbook. 145 137 138 112 137 100 78 127 97 70 143 133 150 124 115 110 45 141 119 92 84 94 105 71 95 117 104 Use the data above to complete the frequency table below: Class Frequency, Class Midpoint Relative Cumulative Boundaries Frequency Frequency 40 - 59 1 39.5-59.5 49.5 3.7% 1 60 - 79 80 - 99 100 - 119 120- 139 140 - 159 Total 27 2. The frequency distribution shows the ages of students volunteering at a local animal shelter. Ages of Student Volunteers (in Years) Class Frequency 10-12 5 13-15 9 16-18 2 19-21 11 22-24 6 a. What is the relative frequency for the 2nd class? b. What is the cumulative frequency for ages 15 and under? c. What percentage of the student volunteers were between the ages of 13 and 21? d. What is the class width? e. How many students were surveyed? f. What was the youngest age of the students surveyed? g. What is the upper class boundary for the 4th class
