2. What is the shape of the histogram?
3. Find the descriptive statistics for the data set (hint: use the Data Analysis Toolpak.
4. Which measure of central tendency better describe the weight of a plan M&M?
5. Based on the shape of the histogram, would it be appropriate to use the Empirical Rule to make any general statements aobut the weights of the M&Ms?
6. Use the Empriical Rule to determine the percentage of M&Ms with weights between 0.803 and 0.947 gram.
7. Determine the actual percentage of M&Ms with weights more than 0.911 gram.
