A simple random sample of 14 different cereals isobtained, and the sugar content(in grams of sugar per gram ofcereal) is measured for each cereal selected. Those amounts have a mean of 0.29 gram and a standard deviation of 0.168 gram. Use a 0.05 significance level to test the claim of a cereal lobbyist that the mean for all cereals is less than 0.31 gram.

Find the test statistic.
