Question 530181: 3.The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight ounce servings (Coca-Cola Company website, February 3, 2009). Suppose you are curious whether the consumption of Coca-Cola beverages is higher in Atlanta, Georgia, the location of Coca-Cola�s corporate headquarters. A sample of 36 individuals from the Atlanta area showed a sample mean annual consumption of 460.4 eight ounce servings with a standard deviation of s = 101.9 ounces. Using α = .05, do the sample results support the conclusion that mean annual consumption of Coca-Cola beverage products is higher in Atlanta?

Ho: u <= 423 oz
Ha: u > 423 oz (claim)
-----------
z(460.4) = (460.4-423)/[101.9/sqrt(36)] = 2.2022
----
p-value = P(z > 2.2022) = 0.0138
---
Conclusion: Since the p-value is less than 5%
reject Ho at the 5% significance level.
The test results support the claim.
