	Bag		Red		Blue

Analyze the data by calculating the following:

1.    

What was the variance and standard deviation of each color?

2.    

What was the variance and standard deviation for the total number of candies?

3.    
Suppose a new bag was opened with the following numbers:

RedBlue

32

4.    
Compute the z-scores for this bag for each color and for the total number of candies.
