7:11 4A nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set byregulations for "reduced sodium" franks. The mean sodium content for the sample was 321.5 mg with a standarddeviation 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 H=325HA: H<325The test statistic is t= - 1.17.(Round to two decimal places as needed.)The P-value is(Round to three decimal places as needed.)<AAmylab.pearson.com..llLTE8
