Ecn 221 The sodium content of a popular sports drink is listed as 206 mg in a 32-oz bottle. Analysis of 14 bottles indicates a sample mean of 217.5 mg with a sample standard deviation of 14.9 mg. (a) State the hypotheses for a two-tailed test of the claimed sodium content.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  206 mg

Sample mean, = 217.5 mg

Sample size, n = 14

Sample standard deviation, s = 14.9 mg

Claim:

The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.

Thus, we design the null and the alternate hypothesis

We use two-tailed t test to perform this hypothesis.
