(6pts) You want to construct a confidence interval for the difference in proportions for the second largest difference color between M&M's and Skittles (the one circled for #6). Assume your bags of M&M's and Skittles are both random samples; verify whether all the requirements are satisfied for constructing this confidence interval. Show work and explain each one. 8. (4pts) Regardless of whether or not the requirements were met above, construct a 90% confidence interval for the difference in proportions of your chosen color for M&M's and Skittles. (Do not show formula or substitution - just state your calculator entry and the result with all decimal places. Let Group 1 = M&M's) 9. (4pts) If the confidence level was increased above 90%, the confidence interval created above would have been: (Circle one) Explain. narrower the same width wider not enough info L
