The manufacturer of Skittles is considering changing the flavor of the green Skittle from lime to green apple. In order to help with that decision, Skittles performs a comparison taste test in St. Louis. Two hundred (200) consumers taste tested the Skittles, and 156 responded that they preferred the lime flavor, while 44 responded they preferred the green apple flavor.1. What is the point estimate of the proportion of consumers who prefer lime flavor over green apple? –Provide all answers that follow to 4 decimal places.–2. At 90% confidence, what is the margin of error for the proportion of consumers who prefer the lime flavor? 3. Provide a 90% confidence interval for the population proportion of consumers who prefer the lime flavor for green Skittles: to 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: to 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?
