We will be constructing confidence intervals for the proportion of each color as well as the mean number of candies per bag. You will use the methods of 9.1 for the proportions and 9.2 for the mean. Remember that you can use Excel (or your calculator) to do many of the preliminary calculations
1). Construct a 95% Confidence Interval for the mean total number of candies (large samples).
(2). Construct a 95% Confidence Interval for the proportion of blue M&Ms® candies.
(3). Construct a 95% Confidence Interval for the proportion of orange M&Ms® candies.
(4). Construct a 95% Confidence Interval for the proportion of green M&Ms® candies.

Calculate the mean, median, and standard deviation for the total number of candies (per bag). Construct a histogram of the total number of candies (per bag). Use the z-score method to identify any potential outliers and outliers. Assume the total number of candies is normally distributed, calculate the probability that a randomly sampled bag has at least 55 candies in a bag. If a random sample of 50 bags is selected, find the probability that the mean number of candies...

A study of reading comprehension in children compared three methods of instruction. The three methods of instruction are called Basal, DRTA, and Strategies. As is common in such studies, several pretest variables were measured before any instruction was given. One purpose of the pretest was to see if the three groups of children were similar in their comprehension skills. The READING data set described in the Data Appendix gives two pretest measures that were used in this study. Use one-way...
