The sodium content of a popular sports drink is listed as 240 mg in a 32-oz bottle. Analysis of 10 bottles indicates a sample mean of 248.2 mg with a sample standard deviation of 18 mg. (a) Write the hypotheses for a two-tailed test of the claimed sodium content. (b) Calculate the t test statistic to test the manufacturer’s claim. (c) At the 5 percent level of significance (α = .05), does the sample contradict the manufacturer’s claim?
