A company with a large fleet of cars hopes to meet the goal of 37 2 mog afor their fleet of cars. To see if the goal is being met, they check the gasoline usage for 42 company trips chosen at random, finding a mean of 40 20 mog and astandard deviation of 6.72 mpg. Is this strong evidence that they have attained their fuel economy goal? Complete parts (a) trough () belica Use 0.05 as the Pcutoffb) Are the necessary assumptions to make inferences satisfied? Choose the correct answer below.O A. The company uses a random sample, so one can assume the data are independent. If there are no outliers, and the data are unimodal, symmetric, and onlymildly skewed, one can assume the data come from a Normal population.O B. The company uses a random sample, so one can assume the data are dependent. If there are no outliers, and the data are unimodal, symmetric, and onlymildly skewed, one can assume the data come from a Normal population.O C. The company uses a random sample, so one can assume the data are dependent. If the sample size is less than 10% of the population, and there are at least10 successes and 10 failures, one can assume the population follows a Student’s t-model.O D. The company uses a random sample, so one can assume the data are independent. If the sample size is less than 10% of the population, and there are atleast 10 successes and 10 failures, one can assume the population follows a Student’s t-model.
