Question
A nutrition lab 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 321.5 mg with a standard deviation of 19 mg. Assume that 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? a) Write appropriate hypotheses. Hoi u = 325 HA: H<325 The test statistic is t= (Round to two decimal places as needed.)
