A bag of M&Ms was randomly selected from the grocery store shelf, and the color counts were:Brown 22 Red 21 Yellow Orange 13 Green 17 Blue Find the 97% confidence interval for the proportion of blue M&Ms in that bag. 22 14
Question 7Your answer is CORRECT.Mars Inc. claims that they produce M&Ms with the following distributions:Brown 30% Red 20% Yellow Orange 10% Green 10% Blue How many M&Ms must be sampled to construct the 98% confidence interval for the proportion of orange M&Ms in that bag if we want a margin of error of ± .14? 20% 10%
