Suppose that 12 bags of skittles contained on average 27.85 pieces of candy with a standard deviation of 2.7 pieces of candy. For the purposes of this exercise, assume that these bags of skittles is representative of all the bags of skittles and distribution number of candies per bag is aproxiamtely normal. Does the sample data provide convincing evidence that the average number of skittles in each bag is less than 30. Test appropriate hypotheses using a .01 significance level, round your statistic to the appropriate number of decimal places to use the correct chart and round everything else to 4 decimal places. Follow the seven step process used in Algorithm 10.9
