Q4: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 ishigher 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 훼=0.05, do the sample results support the conclusion that mean annual consumption of Coca-Cola beverage products is higher in Atlanta?
Below are the null and alternative Hypothesis,
Null Hypothesis: μ = 423
Alternative Hypothesis: μ > 423
Rejection Region
This is right tailed test, for α = 0.05 and df = 35
Critical value of t is 1.69.
Hence reject H0 if t > 1.69
Test statistic,
t = (xbar - mu)/(s/sqrt(n))
t = (460.4 - 423)/(101.9/sqrt(36))
t = 2.202
P-value Approach
P-value = 0.0172
As P-value < 0.05, reject the null hypothesis.
Rejection Region Approach
As the value of test statistic, t is outside critical value range,
reject the null hypothesis

2) What were some of the key challenges they encountered? How did they overcome them? 3) What were some of the key takeaways they learned to use in the future? When I assumed the leadership of Heinz’s Asia/Pacific business, in 1993, the company’s revenues from that part of the world were hardly a blip—and I’d never visited most of the countries in the region. I made my first trip there soon after I took the job, and it really opened...
