Stuck on this problem in my study guide. Help if you can!

Congress regulates corporate fuel economy and sets an annual gas mileage for cars. A company with a large fleet of cars hopes to meet the goal of 33.7 mpg or better for their fleet of cars. To see if the goal is being met, they check the gasoline usage for 46 company trips chosen at random, finding a mean of 36.70 mpg and a standard deviation of 6.88 mpg. Is this strong evidence that they have attained their fuel economy goal? Use 0.05 as the level of significance. What conditions are necessary for us to perform a hypothesis for attaining the mean fuel economy for the fleet of cars (p)? Select one: A 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 only mildly skewed, one can assume the data come from a Normal population. A 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 only mildly skewed, one can assume the data come from a Normal population. A 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 least 10 successes and 10 failuresl one can assume the population follows a Student's t-model. A 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 populationl and there are at least 10 successes and 10 failures, one can assume the population follows a Student's t-model
