Question: Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Use the P-value method.
Data set 16 in Appendix B lists the sugar content (grams of sugar per gram of cereal) for a sample of different cereals. Those amounts are summarized with these statistics: n= 16, xbar= 0.295, s= 0.168g. Use a 0.05 significance level to test the claim of a cereal lobbyist that the mean for all cereals is less than 0.3g.
