Players paid $20 to spin the spinner once and collected the prize where the arrow landed. Unfortunately, the non-profitlater discovered that this game paid out more money than it took in. They want to use the spinner again this year but need it be profitable for the charityand still attractive to players.$20$50$5$80a.

After running a mile a day over a period of two weeks, the average amount of weight loss is 2.5 pounds. A dietitian, who publishes health articles in a newspaper, states their new diet program helps with additional weight loss when combining their special diet with running a mile a day over a period of two weeks. Interested in studying the dietitian's article further, you ask friends who have tried the dietitian's new program and you determine their weight loss to be 3.0 pounds in a two-week period, on average. As you set up a hypothesis test to determine if the dietitian's article is correct, what is the dietitian's claim?
Andrea ws visiting her Uncle Ralph who has a large gumball collection. When she asked if she could have some, he said yes, but only if she could solve a problem. He told her that he has three jars, each covered so that no one can see the color of gumballs inside. One jar is labeled red, the second green, and the third red-green. However, he said that no jar has the correct label on it. She could reach into one jar and take one gumball. Then she had to tell him the correct color of gumballs in each jar. she reached into the jar labeled red-green and pulled out a red gum ball. Are there any green gumballs in that jar?
Blake and April are both taking AP Calculus, but they have different teachers who have two different grading systems. Blake is in Mr. Frey’s class and April is in Coach Smith’s class. Blake is mad because she thinks that with her averages, she would have a higher average in Coach Smith’s class. Given her averages below, what would be her overall average for each class?

For the remainder of this question, we will consider one of the world's most popular video games, Minecraft (adapted from Mills & Mills, 2016). In this game, the character (you) can attempt to tame a wolf with a bone. Assume that you get 9 tries to tame the wolf, i.e. there are 9 bones. Each time you tame the wolf, the wolf becomes a dog and a new wolf appears which you can then attempt to also tame. This continues until you have used up all 9 bones, and the goal is to end up with as many dogs as possible at the end of the game. The probability of taming the wolf with each attempt is fixed at 0.54. Let X denote the number of dogs at the end of the game so that X BIN (9,0.54). Assume you are about to play the game. 12. What is the probability you will tame less than 4 dogs?
An instructor gave students the option to purchase an interactive program that allows them to answer questions during class and receive credit for participating. Alternatively, students could work an extra problem during weekly homework assignments. The instructor randomly selected 10 students, then randomly divided them into two groups of five each. One group was provided the interactive tool, the other group was asked to work the extra problem. The instructor knew from prior experience that the interactive tool increases attendance. The table below contains the final exam scores for the 10 students (on a scale from 0 to 100). Interactive: 65 78 84 88 96 Extra problem: 56 61 70 75 82 The instructor wishes to test whether increased attendance throughout the semester leads to improved exam scores. Let µ I = mean score that would be observed if all students used the interactive tool and µ E = mean score if all students worked an extra problem. The degrees of freedom, using a t table…
The sport of Professional Bull Riders (PBR) is a world-wide phenomenon where riders mount a bull with the intention of staying on the bull for at least eight seconds as the bull spins, kicks, and twists attempting to throw, or buck, them off. If a rider does not successfully ride for eight seconds, then no points are earned. Each eight-second ride is worth up to 100 points where 50 points is for the bull's performance and 50 points is for how adept the rider is. When judging the bull, judges look at how hard a time the bull gives the rider; the harder the ride, the more points are awarded. Generally, bulls who display more power, speed, and agility are awarded more points. We will explore some data regarding the bulls from the 2019 PBR season. The dataset consists of the bull's name, average time when a rider was bucked off a bull (Avg Buckoff Time), and each bull's average score (Avg Bullscore). The first five rows of the data look like this. + Name SMOOTH OPERATOR SMOOTH WRECK…
At a raffle, 100 tickets are sold for 1 prize of $100 and 3 consolation prizes of $20. What price should the tickets be sold for if the goal is to make the raffle a fair game?
A chef is trying out a new recipe he has been working on and wants to see if it will sell better than his old one. To find out, he performs an experiment where he randomly assigns 20 people to try his new recipe and 20 people to try his old one. He asks each group how much they would be willing to pay for their food, and he finds that the group with the old recipe would pay an average of $20.00 and the second would pay an average of $26.00. He then performs an independent samples t-test between these groups. a. Suppose the sample variance for the price of the chef’s old recipe is $2.00, and the sample variance for the new recipe is $3.00. Perform a one-tailed t-test at a significance level of α = 0.01 and explain what the result means (how does the new recipe compare to the old one?). b. To evaluate the magnitude of effect size, compute the estimated Cohen’s d. Briefly describe what it means, and comment on the strength of the effect: is it weak, moderate or strong?
Bob and Doug play a lot of Ping-Pong, but Doug is a much better player, and wins 60% of their games. To make up for this, if Doug wins a game he will spot Bob five points in their next game. If Doug wins again he will spot Bob ten points the next game, and if he still wins the next game he will spot him fifteen points, and continue to spot him fifteen points as long as he keeps winning. Whenever Bob wins a game he goes back to playing the next game with no advantage. It turns out that with a five-point advantage Bob wins 70% of the time; he wins 80% of the time with a ten-point advantage and 90% of the time with a fifteen-point advantage. Model this situation as a Markov chain using the number of consecutive games won by Doug as the states. There should be four states representing zero, one, two, and three or more consecutive game won by Doug. Find the transition matrix of this system, the steady-state vector for the system, and determine the proportion of games that Doug will win in…
