how many cars would you predict would run the red light?” Use the following scenario for 25 only. Use the method of regression analysis to test the relationsp between temperature (X) and the number of cars recorded as speeding (Y). Set α = .05 Temperature Number of Cars Speeding 50 10 65 12 80 16 85 16 90 |
Quiz 11 Questions 21-24 refer to the following situation: On s morning commute, a researcher notices that the shorter the interval of time between traffic light changes, the more vecles run the red light. Interested in ts relationsp, the researcher conducts an experiment over the next few weeks. Each morning he first chooses a traffic light at random. Once the light changes, he begins counting the number of vecles running red lights. He continues to count until the light changes again. The data on six lights is as follows: Length of Light (X) Number of Cars (Y) 10 20 13 19 19 17 25 11 28 9 30 8 21. Calculate the regression line. 22. What is the Y-intercept? 23. Calculate the coefficient of determination. 24. “If the length of a light was 7 seconds, how many cars would you predict would run the red light?” Use the following scenario for 25 only. Use the method of regression analysis to test the relationsp between temperature (X) and the number of cars recorded as speeding (Y). Set α = .05 Temperature Number of Cars Speeding 50 10 65 12 80 16 85 16 90 13 70 10 75 12 25. Use the method of regression analysis to test the relationsp between temperature (X) and the number of cars reordered as speeding (Y). Set __=.05
