    M&M Project: Part 3

    Use the M&M data to complete this assignment. StatCrunch can be used to assist with the calculations. A link for StatCrunch can be found under Tools for Success in Course Home. Here is also a link:

    If calculating by hand, be sure to keep at least 4-6 decimal places for the sample proportions to eliminate large rounding errors.

    o Construct a 95% Confidence Interval for the proportion of blue M&M candies.

    o Construct a 95% Confidence Interval for the proportion of orange M&M candies.

    o Construct a 95% Confidence Interval for the proportion of green M&M candies.

    o Construct a 95% Confidence Interval for the proportion of yellow M&M candies.

    o Construct a 95% Confidence Interval for the proportion of red M&M candies.

    o Construct a 95% Confidence Interval for the proportion of brown M&M candies.

    o Construct a 95% Confidence Interval for the mean total number of candies (large samples).

    o BONUS: How many candies should be sampled to obtain a 95% CI of the proportion of blue candies with a 4% margin of error if the known proportion of blue candies is 0.24?
