Attached are two data sets, one concerning Skittles and one about cereals. You may assume both samples provided were selected randomly and are representative of the population. Be sure to use the correct data set with each of the following questions. Round all proportions to 4 decimal places, all means and standard deviations to 3 decimal places, all z-critical values and t-critical values to 2 decimal places, all z* values (z test statistic) to 2 decimal places, all t* values (t test statistic) to 1 decimal place, all P-values for hypothesis tests dealing with proportions to 4 decimal places, and all P-values for hypothesis tests dealing with means to 3 decimal places.

1. Create a 99% confidence interval for the proportion of cereals that have more than 150mg of SODIUM per serving based on the samples provided.
2. Use a hypothesis test to check if cereals have more than an average of 2g of PROTEIN. Use the attached data with a significance level of .05.
3. Suppose that my favorite colors are RED and PURPLE, and I hate all other colors of Skittles. Is there enough evidence that given a random package of Skittles that the proportion of my FAVORITE COLORS will be less than the proportion of my HATED COLORS? Use the attached data with the significance level of .01.
4. Find a 95% confidence interval that looks at the difference between the average number of RED Skittles in a package and the average number of ORANGE Skittles in a package based on the samples provided.
