Provide a 90% confidence interval for the population proportion of consumers who prefer the lime flavor for green Skittles: Provide your answers to 4 decimal places. [LoCI90] to [HiCI90] 4. Looking now at the weird consumers who prefer the green apple flavor (after all, Skittles shouldn't be sour tasting--yuck), provide a 95% confidence interval for the population proportion of consumers who prefer the green apple flavor for green Skittles: Provide your answers to 4 decimal places. [LoCI95] to [HiCI95] 5. After the taste testing in St. Louis, Skittles plans to do another round of taste testing next week in Denver. Skittles wants to increase the confidence or probability to 99% with a margin of error of 4% (.04). How many people should Skittles sample at the taste testing event in Denver? [n]
