Math Problem Statement
Let’s assume that 24% of all M&M’s are blue. This means the population proportion of M&M’s that are blue is p = 0.24. Suppose random samples of 25 M&M’s are obtained and the proportion of blue M&M’s are found. The image below displays a simulated distribution of 300 sample proportions of M&M’s that are blue, for samples of size n = 25. Estimate the mean of the sample proportions from the dotplot.
