Solution

For \"Are there a greater proportion of blue M&Ms in a milk chocolate bag than in a peanut bag?\", Difference between Proportions using Two Independent Samples will be used. Because there are two independent samples one from each bag. and then proportion of blue M&Ms will be compared.

For \" Are the colors evenly distributed in either bag? \" Goodness of fit test (chi sqaure test) should be used. Here we used observed frequncies of each color in bag and compared them with expected frequencies of the colors.
