Final answer:
Estimating how many peanut M&Ms fit in a 12 oz jar requires a mathematical approach involving volume estimation of both the candy and the jar, which is not directly related to the nutritional composition of the candies.
Step-by-step explanation:
The question 'how many peanut M&Ms fit in a 12 oz jar?' falls within the domain of Mathematics, particularly in dealing with volume and estimation. To calculate the number of peanut M&Ms that can fit in a 12 oz jar, one could hypothetically conduct an experiment akin to the Candy Survey, although the survey's purpose is actually to compare the mean number of candy pieces between two brands rather than determining volume capacity.
One method to approach this question would be to fill a 12 oz jar with peanut M&Ms and count them directly. However, without performing this experiment, a more mathematical approach would involve estimating based on the average volume of a single M&M and the volume of the jar. Furthermore, assessing the nutritional information of the peanut M&Ms, as in the jar of peanut butter example, while health informative, will not directly aid in determining how many M&Ms the jar can hold.
