The sodium content of a popular sports drink is listed as 200 mg in a 32-oz bottle. analysis of 20 bottles indicates a sample mean of 211.5 mg with a sample standard deviation of 18.5 mg.
(a)
state the hypotheses for a two-tailed test of the claimed sodium content.
h0: µ = 200 vs. h1: µ ≠ 200
h0: µ ≥ 200 vs. h1: µ < 200
h0: µ ≤ 200 vs. h1: µ > 200
(b)
calculate the t test statistic to test the manufacturer’s claim.
(c)
at the 5 percent level of significance (α = 0.05) does the sample contradict the manufacturer’s claim?
or do not h0. the sample or does not the manufacturer's claim.
(d-1)
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)?
