The sodium content of a popular sports drink is listed as 220 mg in a 32-oz bottle. Analysis of 10 bottles indicates a sample mean of 228.2 mg with a sample standard deviation of 18.2 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? (d) Use Excel to find the p-value and compare it to the level of significance. Did you come to the same conclusion as you did in part (c)?
