The sodium content of a popular sports drink is listed as 225 mg in a 32-oz bottle. Analysis of 15 bottles indicates a sample mean of 233.0 mg with a sample standard deviation of 25.0 mg.
(a)State the hypotheses for a two-tailed test of the claimed sodium content.
a.H0: μ ≥ 225 vs. H₁ : μ < 225
b.H0: μ ≤ 225 vs. H₁ : μ > 225
c.H0: μ = 225 vs. H₁ : μ ≠ 225
