Extracted text: A car company says that the mean gas mileage for its luxury sedan is at least 24 miles per gallon (mpg). You believe the claim is incorrect and find that a random sample of 6 cars has a mean gas mileage of 21 mpg and a standard deviation of 2 mpg. At a = 0.10, test the company's claim. Assume the population is normally distributed. Click here to view the t-distribution table. Click here to view page 1 of the normal table. Click here to view page 2 of the normal table. ..... Which sampling distribution should be used and why? A. Use a normal sampling distribution because the population is normal, and o is known. B. Use a t-sampling distribution because the population is normal, and o is known. O C. Use a normal sampling distribution because n> 30. D. Use a t-sampling distribution because the population is normal, and o is unknown. E. Use a normal sampling distribution because the population is normal, and o is unknown. F. Use a t-sampling distribution because n< 30.="" state="" the="" appropriate="" hypotheses="" to="" test.="" b.="" h="" ,="" μ2="" 24="" ο="" α.="" ho:="" μ="" 24="" ha:="" µ=""> 24 Ha: H<24 o c. ho: h+ 24 d. ho , μ= 24 hạ: h = 24 hai h#24 %3d what is the value of the standardized test statistic? the standardized test statistic is|.
