Joe likes to go to an old arcade and play 12 games of Skeeball every day. On average, he wins a prize on 55% of the games he plays. Today, however, he won only 4 of the 12 games he played.This made Joe think that there must be something wrong with how he is throwing the ball today. However, a friend tells him, "You might be throwing the same way you usually do. People will sometimes have a group of bad games just because of random variation, not because of psychology, or because they are doing anything differently, or any other reason. For someone with your statistics, such random bad days wouldn't even be very rare."Let's see what Joe's friend means. Suppose that Joe's skill level really hasn't changed, so he still has a 55% chance of winning each game he plays, like before. If he plays 12 games a day, on what percentage of days will he win 4 games or fewer? Assume that each game is independent of the others.

- In your Statistics class, your final grade is based on four categories. The categories are tests, labs, assignments, and a final exam. Suppose you earned the following grades in each of the categories; 76% on tests, 88% on labs, 97% on assignments, and 51% on the final exam. If tests are worth 22%, labs are worth 5%, assignments are worth 14%, and the final exam is worth 59%, determine your final grade in the course.

Their poll asked likely Nevada voters who they intend to vote for. The results were: Catherine Cortez Masto with 45%, Adam Laxalt with 41%, 14% undecided, and they report that their poll has a +/- 3.5 percentage point margin of error. The article's headline is "Cortez-Masto Leads Laxalt by 4 Points." Is the R-J right? That is, can we be reasonably sure (95% confident) that Cortez-Masto really is ahead of Laxalt? if we had the raw data we could just load it into R and do a quick difference of means test, but we don't need the actual data to figure it out in this case. In your answer, address the following: (1) Is the R-J probably right that Cortez-Masto leads Laxalt? (2) how you came to that conclusion?arrow_forward
