Statistics students found the sugar content of breakfast
cereals, in grams per serving, for those placed on the high shelves of the
store versus the low shelves. The data fi le CerealSugar.txt has these results.
Copy and paste this data set into the Descriptive Statistics applet.

a.      
If you want to compare the sugar content of cereals on high versus low
shelves, what would be the explanatory variable and what would be the response.

b. Based on just how the
distributions look, do you think there is an association between where the
cereal is located and its sugar content? If so, in what way? Explain.

c. Find the mean grams of sugar
per serving for the cereal on the low shelves and the mean for those on the
high shelves. With this new information, do you think there is an association
between where the cereal is located and its sugar content? Explain.

 d. Find the median grams of sugar
per serving for the cereal on the low shelves and the median for those on the
high shelves. With this new information, do you think there is an association
between where the cereal is located and its sugar content? Explain.

 e. Are the median sugar contents
between high and low shelved cereal farther apart or closer together than the
means are?
