- a. Conduct a test to determine whether the true mean willingness to eat the brand of sliced apples packaged for children exceeded 3. Use α = .05 to make your conclusion.
- b. The data (willingness to eat values) are not
normally distributed. How does this impact (if at all) the validity of your conclusion in part a? Explain.
