You record the age, marital status, and earned income of a sample of 1463 women. The number and typeof variables you have recorded is  \n• (a) 3 quantitative, 0 categorical  \n• (b) 4 quantitative, 0 categorical  \n• (c) 3 quantitative, 1 categorical  \n• (d) 2 quantitative, 1 categorical  \n• (e) 2 quantitative, 2 categorical  \nT1.2 . Consumers Union measured the gas mileage in miles per gallon of 38 vehicles from the same model year on a special test track. The pie chart provides information about the country of manufacture of the model cars tested by Consumers Union. Based on the pie chart, we conclude  \n• (a) Japanese cars get significantly lower gas mileage than cars from other countries.  \n• (b) U.S. cars get significantly higher gas mileage than cars from other countries.  \n• (c) Swedish cars get gas mileages that are between those of Japanese and U.S. cars.  \n• (d) Mercedes, Audi, Porsche, and BMW represent approximately a quarter of the cars tested.  \n• (e) More than half of the cars in the study were from the United States.  \nT1.3. Which of the following bar graphs is equivalent to the pie chart in Question T1.2?  \n(a) (b)  \n(c) (d)  \n(e) None of these.  \nT1.4. Earthquake intensities are measured using a device called a seismograph, which is designed to be most sensitive to earthquakes with intensities between 4.0 and 9.0 on the Richter scale. Measurements of nine earthquakes gave the following readings:  \nwhere L indicates that the earthquake had an intensity below 4.0 and an H indicates that the earthquake had an intensity above 9.0. The median earthquake intensity of the sample is  \n• (a) 5.75.  \n• (b) 6.00.  \n• (c) 6.47.  \n• (d) 8.70.  \n• (e) Cannot be determined.  \nQuestions T1.5 and T1.6 refer to the following setting. In a statistics class with 136 students, the professor records how much money (in dollars) each student has in his or her possession during the first class of the semester. The histogram shows the data that were collected.  \nT1.5. The percentage of students with less than $10 in their possession is closest to • (a) 30% .  \n• (b) 35% .  \n• (c) 50% .  \n• (d) 60% .  \n• (e) 70% .  \nT1.6. Which of the following statements about this distribution is not correct?  \n• (a) The histogram is right-skewed.  \n• (b) The median is less than $20.  \n• (c) The IQR is $35.  \n• (d) The mean is greater than the median.  \n• (e) The histogram is unimodal.  \nT1.7. Forty students took a statistics examination having a maximum of 50 points. The score distribution is given in the following stem-and-leaf plot:  \nThe third quartile of the score distribution is equal to  \n(a) 45 (b) 44 (c) 43 (d) 32 (e) 23  \nT1.8 . The mean salary of all female workers is $35,000 . The mean salary of all male workers is $41,000 . What must be true about the mean salary of all workers?  \n• (a) It must be $38,000 .  \n• (b) It must be larger than the median salary.  \n• (c) It could be any number between $35,000 and $41,000 .  \n• (d) It must be larger than $38,000 .  \n• (e) It cannot be larger than $40,000 .  \nQuestions T1.9 and T1.10 refer to the following setting. A survey was designed to study how business operations vary according to their size. Companies were classified as small, medium, or large. Questionnaires were sent to 200 randomly selected businesses of each size. Since not all questionnaires in a survey of this type are returned, researchers decided to investigate the relationship between the response rate and the size of the business. The data are given in the following two-way table:  \nT1.9. What percent of all small companies receiving questionnaires responded?  \n(a) 12.5% (b) 20.8% (c) 33.3% (d) 50.8% (e) 62.5%  \nT1.10. Which of the following conclusions seems to be supported by the data?  \n• (a) There are more small companies than large companies in the survey.  \n• (b) Small companies appear to have a h","cbCaiaqh3dqj0jMf","https://ap.wps.com/l/cbCaiaqh3dqj0jMf","pdf",359765,"English","# Section I: Multiple Choice\n## T1.1 to T1.4\n## T1.5 to T1.8\n## T1.9 to T1.11\n# Section II: Free Response\n## T1.12","[{\"question\":\"How do you determine the number of quantitative versus categorical variables in the T1.1 scenario?\",\"answer\":\"Identify each recorded variable as quantitative (numeric measurements) or categorical (labels/categories).
