Identify whether the statement describes inferential statistics or descriptive statistics. 2) The average age of the students in a statistics class is 19 years. Identify the data set's level of measurement. 3) temperatures of 12 selected refrigerators 4) marriage status (married, single, or divorced) of the faculty at the University of Colorado 5) the ratings of a movie ranging from "poor" to "good" to "excellent" 6) number of milligrams of tar in 85 cigarettes Determine whether the data are qualitative or quantitative. 7) the number of seats in a movie theater 8) the colors of automobiles on a used car lot Identify the sampling technique used. 9) A researcher randomly selects and interviews fifty male and fifty female teachers. 10) To ensure customer satisfaction, every 20th phone call received by customer service will be monitored. 11) To avoid working late, the quality control manager inspects the last 50 items produced that day. 12) A researcher randomly selected 25 of the nation's middle schools and interviewed all of the teachers at each school. 13) A lobbyist for a major airspace firm assigns a number to each legislator and then uses a computer to randomly generate ten numbers. The lobbyist contacts the legislators corresponding to these numbers. 14) Find the mean, median, and mode of the following numbers: ) A student receives test scores of 62, 83, and 91. The student's final exam score is 88 and homework score is 76. Each test is worth 20% of the final grade, the final exam is 25% of the final grade, and the homework grade is 15% of the final grade. What is the student's mean score in the class? 1.tst
2 Use the given frequency distribution to find the (a) class width. (b) class midpoints of the first class. (c) class boundaries of the first class. 16) Phone Calls (per day) Class Frequency, f Use the grouped data formulas to find the indicated mean or standard deviation. 17) For the following data set, approximate both the sample mean and the sample standard deviation. Phone calls (per day) Frequency The Highway Patrol, using radar, checked the speeds (in mph) of 30 passing motorists at a checkpoint. The results are listed below ) Construct a frequency histogram using six classes. Then describe the shape of the curve. 19) For the stem-and-leaf plot below, find the 5 number summary, range, and interquartile range (IQR). Key: 2 7 = ) For the mathematics part of the SAT the mean is 514 with a standard deviation of 113, and for the mathematics part of the ACT the mean is 20.6 with a standard deviation of 5.1. Bob scores a 660 on the SAT and a 27 on the ACT. Use z-scores to determine on which test he performed better.
3 21) The mean IQ score of adults is 100, with a standard deviation of 15. Use the Empirical Rule to find the percentage of adults with scores between 70 and 130. (Assume the data set has a bell-shaped distribution.) 22) The mean SAT verbal score is 428, with a standard deviation of 97. Use the Empirical Rule to determine what percent of the scores lie between 428 and 525.
