Read the following case and test the hypothesis: The average American eats 9.5 pounds of chocolate annually. Suppose you are curious whether chocolate consumption is higher in Hershey, Pennsylvania, the location of The Hershey Company’s corporate headquarters. A sample of 36 individuals from the Hershey area showed a sample mean annual consumption of 10.05 pounds and a standard deviation of s=1.5 pounds. Using α= .05, do the sample results support the conclusion that mean annual consumption of chocolate is higher in Hershey than it is throughout the United States? Please use excel for solution and formula

Expert Solution
Step 1
Given information
Hypothesized mean µ = 9.5 pounds
Sample size (n) = 36
Mean x̅ = 10.05 pounds
Standard deviation (s) = 1.5 pounds
Significance level, α = 0.05
Hypothesis
Null Hypothesis: Ho: µ = 9.5
Alternative Hypothesis: Ha: µ > 9.5
We need to test the claim that mean annual consumption of chocolate is higher in Hershey than it is throughout the United States.
