Joe likes to go to an old arcade and play 8 games of Skeeball every day. On average, he wins a prize on 65% of the games he plays. Today, however, he won only 3 of the 8 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 throwir 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 65% chance of winning each game he plays, like before. If he plays 8 games a day, on what percentage of days will he win 3 games or fewer? Assume that each game is independent of the others. Fill in the blank: Joe would win 3 games or fewer on % of the days that he plays. (Round to one decimal place as needed)

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

Joe likes to go to an old arcade and play 8 games of Skeeball every day. On average, he wins a prize on 65% of the games he plays. Today,
however, he won only 3 of the 8 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 65% chance of winning each game he
plays, like before. If he plays 8 games a day, on what percentage of days will he win 3 games or fewer? Assume that each game is independent of
the others.
Fill in the blank: Joe would win 3 games or fewer on % of the days that he plays.
(Round to one decimal place as needed.)

Sarah chose to live on the honors floor of her dorm because she was told that the students on that floor would be quiet and studious. She was told that students on the honors floor study 10.5 hours per week. After living on the honors floor for a few months, Sarah is convinced that the students around her study less than 10.5 hours a week. To test her claim, Sarah polls 10 students on her floor regarding the number of hours per week that they spend studying. Use the results in the table below to test Sarah’s claim at the 0.05 level of significance. Assume that the population distribution is approximately normal. hours of study: 12,4,14,9,8,6,10,12,11,9

In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times landing tails up compared to the penny. The students are instructed to spin the penny and the dime 30 times and record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Let PD = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. Which of the following is the correct standardized test statistic and P-value for the hypotheses, Ho: Po-Pp= 0 and H₂: Po-Pp<0?
