Final Answer:
Due to the lack of the actual data set provided, it is not possible to determine the shape of the distribution, create a histogram, or perform statistical analysis. Please provide the dataset for a more accurate response.
Step-by-step explanation:
The questions posed require access to the specific M&M weights dataset mentioned in the "M&Ms Data" tab. Unfortunately, without the actual data, it is impossible to generate a frequency histogram, determine the shape, or conduct statistical analyses. The Data Analysis Toolpak is suggested for descriptive statistics, but its use is contingent on having the dataset. The questions related to the Empirical Rule and percentage calculations also rely on the actual numerical values. Therefore, the answers are currently unattainable without the dataset.
