Suppose you are given the following frequency table that conveys the results of a recent survey of people walking dogs at Hendry's beach. Each respondent was asked how many dogs they have. (All respondents had between 0 and 7 dogs): Number Relative of Dogs Frequency Frequency 0-2 12 3-5 6 5-7 What is the relative frequency of the 0-2 dog class? (Round to the nearest percent, and only include the numerical portion of your answer/do not include the percent sign. e.g. if I calculated 52.864%, my answer would just be 53.) Answer:You are a police officer in Goleta and its Halloween. As usual, roadblocks are set-up at various points throughout the city to combat drunk driving. Throughout the evening you and your fellow officer are giving random drivers breathalyzer tests. Around 2 am you randomly pull over a vehicle and have the driver take a breathalyzer test, the result is positive, and you arrest the driver for drunk driving. We know that the breathalyzer test always detects a truly drunk person, but typically only 9 in 1000 drivers are drunk. It is also true that the overall probability of a positive test is 3%. What is the probability that the driver is drunk AND we get a positive test result? O a. 0.021 O b. Not enough information given to calculate O C. 0.009 O d. None of the above O e. 1.000 Of. 0.9788 O g. 0.991You are a police officer in Goleta and its Halloween. As usual, roadblocks are set-up at various points throughout the city to combat drunk driving.
