Suppose you are interested in the true proportion of red Skittles. Your instructor will compile the data from the entire class and post the number of skittles of each color and the total number of Skittles that were observed below. Check the conditions for computing a 95% confidence interval for
using the class data. State whether or not the conditions are met and whether you believe the results you obtain in step B will be valid. Note: Even though the bags of Skittles in the class data set were selected conveniently by students, the Skittles were placed into the bags using an objective device (the machinery at the factory).
