Question

For each of the following problems, (a) Write the important information, (b) Verify the CLT conditions, (c) Draw the appropriate shade region, (d) Use StatCrunch to calculate the probability. 

  1. The last time such statistics were available on the M&M’s website (they have since been removed),  the stated proportion of blue M&M’s was 24%. Since Joel’s favorite M&M color is blue (he says  they taste like the sky…) he usually hopes to get more blue than usual. If he takes a simple random  sample of 55 M&M’s (about equal to one regular sized pack), what is the probability that he will get  more than 30% blue M&M’s?
