  1. A person who is interested in estimating the proportion of Reese’s Pieces that are orange collects a random sample of 150 Reese’s Pieces, and from this creates the following bootstrap distribution.

               

       a).  How many dots are on the dotplot?  What does each dot represent?




       b).  What does the 0.481 that is located around the middle of the distribution tell you?




       c).  Use the standard error to find a 95% CI for the proportion of all Reese’s Pieces
             that are orange.




       d).  Find a 95% CI for the proportion of all Reese’s Pieces that are orange by using the
             percentile method.
