Question
A research article reported that for a random sample of 850 meal purchases made at fast food chain A, the mean sodium content was 1,681 mg, and the standard deviation was 822 mg. For a random sample of 2,107 meal purchases made at fast food chain B, the mean sodium content was 1,474 mg, and the standard deviation was 817 mg. Based on these data, is it reasonable to conclude that there is a difference in mean sodium content for meal purchases at fast food chain A and meal purchases at fast food chain B? Use ? = 0.05. (Use ?1 for fast food chain A and ?2 for fast food chain B.)
State the appropriate null and alternative hypotheses.
Find the test statistic and P-value. (Use SALT. Round your test statistic to one decimal place and your P-value to three decimal places.)
