The M&M’s in your bag are a sample which will represent the population of all M&M’s. Record how many blue M&M’s are in your bag and the total number of M&M’s. Color Number Blue 15 Total 54 Suppose you wish to find a confidence interval for the proportion of M&M’s that are blue. Would your sample satisfy the assumptions? Explain. 2.Use your sample to obtain a 90% confidence interval for the proportion of M&M’s that are blue. 3. M&M’s website states that 24% of all M&M’s are blue. At the 10% significance level, do your data provide sufficient evidence to conclude that the percentage of blue M&M’s differs from 24%?
