The nutrition lab in Chapter 14, exercise 38 tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks. The mean sodium content for the sample was 322.0 mg with a standard deviation of 18 mg. Assume the assumptions and conditions for the test are met. A) Test the hypothesis that the mean sodium content meets the regulation.

B) Will a larger sample size ensure that the regulations are met?
