The mean potassium content of a popular sports drink is listed as 149 mg in a 32-oz bottle. Analysis of 22 bottles indicates a sample mean of 148.4 mg. (a) State the hypotheses for a two-tailed test of the claimed potassium content. a. He: H=149 mg vs. H₁: #149 mg b. He: 149 mg vs. H₁: >149 mg c. He: 2149 mg vs. H₁: <149 mg O a Ob Oc (b) Assuming a known standard deviation of 3 mg, calculate the z test statistic to test the manufacturer's claim. (Round your answer to 2 decimal places. A negative value should be indicated by a minus sign.) Test statistic
