We have two different samples - consisting of bags of M&M's.

The first sample consists of 5 bags of M&M's with the following number of blue pieces in each bag 10, 11, 9,10,10.

Calculate:
A. The mean
B. The standard deviation
C. The variance
The second sample consists of 10 bags with an average number of blue pieces of 8, and a standard deviation of 1
D. State the null hypothesis and the Alternate hypothesis - referring to whether or not these bags of M&M's are statistically different or not.
E. Do a hypothesis test to determine if the null hypothesis is true. At a .05 significance level.
