Data on the fuel economy of several 2010 model vehicles are given in the accompanying table. Complete parts (a) and (b) below. E Click the icon to view the table of fuel economy data. a) Find and interpret a 95% contidence interval tor the gas mileage of 2010 vehicles. Select the correct choice below and fill in the answer boxes within your choice. (Round to two decimal places as needed. Use ascending order.) O A. 95% of all cars like the ones in the sample have gas mileages between mpg and mpg. Table of mpg values O B. One is 95% confident that the gas mileage of a randomly selected car like the ones in the sample is between mpg and mpg. Car mpg O O C. The true mean gas mileage for cars like the ones in the sample is between mpg and mpg 95% of the time. 1 20 2 25 mpg and mpg. O D. One is 95% confident that the true mean gas mileage for cars like the ones in the sample is between 37 3 4 25 31 b) Does this confidence interval capture the mean gas mileage for all 2010 vehicles? Choose the correct answer below. 31 39 23 O A. Without knowing how the data were selected, one must be cautious about generalizing to all 2010 cars. B. There is a 95% chance that this interval contains the true mean gas mileage for all 2010 vehicles. 39 35 26 26 23 O C. Because the sample size is more than 10% of the population, the inferences drawn from the confidence interval are not valid. 39 26 View an example Ask my instructor Help me solve this 82°F P Type here to search- 144 17 f6 ts f3 f4 IOI 米 12 5678901招供何_
