6. A dietician obtains the amounts of sugar ( in centigrams) from 100 centigrams( or 1 gram) in each of 10 different cereals, including Cherios, Corn Flakes, Fruit Loops, ands 7 others. Those values are listed below. Is the mean of those values likely to be a good estimate of the mean amount of the sugar in each gram of cereal consumed by the population of all Americans who eat cereal? Why or Why not?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi finitehelp;
Don't mention it but please use my username, I don't want anyone to know my first name.

Re: mean
Hi momofmathkid;
Empirical evidence doesn't support your statement. Out of 1785 people polled only 11 were able to guess my first name by looking at my username.
