Suzanne has injured her leg and may not be able to play in the next lacrosse game. If she can play, the coach estimates that the team will score 8 points. If she is not able to play, the coach estimates that the team will score 4 points. The doctor states there is a 40% chance that she will be able to play and a 60% chance that she will not be able to play. Determine the expected number of points that the team will scor

Luke's teacher has assigned each student in his class an online quiz, which is made up of 10 multiple-choice questions with 4 options each. Luke hasn't been paying attention in class and has to guess on each question. However, his teacher allows each student to take the quiz three times and will record the highest of the three scores. A passing score is 6 or more correct out of 10. We want to perform a simulation to estimate the score that Luke will earn on the quiz if he guesses at random on all the questions. The dotplot shows Luke's simulated quiz score in 50 trials of the simulation. Doug is in the same class and claims to understand some of the material. 1 N 10000 2 …………………………………at 3 …………………… 4 3 ……………………●●●●●▬ 5 Simulated quiz score -●●●●● 10 6 7 If Doug scored 8 points on the quiz, is there convincing evidence that he understands some of the material? Why or why not? Yes, it is unlikely that Doug would score higher than 6 out of 10 based upon randomly guessing the answers. Since…

Sean is the star shortstop for his baseball team. He notices that his team typically scores about half as many runs as he has singles, and that his team is about 10% more likely to win a game for each run scored. How likely is it that the team wins if he has 6 singles? How many singles did Sean hit if the team was 70% likely to win?
All athletes participating in a high school sports league are required to be tested for steroid use. Those who fail are barred from competition for the rest of the year. Research shows that the specific test used for steroids is 95% accurate. Unknown to the coaches, 4% of the athletes actually use steroids. If there are 500 athletes in the league, how many of them are likely to fail the test? How many of those are false accusations, resulting in athletes being incorrectly suspended from play? athletes will fail the test, out of the 500 athletes tested. of the athletes who tested positive for steroids actually do not use steroids. They were falsely accused.
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 with 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 pp = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. The P-value for this significance test is 0.296. Which of the following is the correct conclusion for this test of the hypotheses H Pp-Pp=0 and H, Po-Pp 0.05. There is sufficient evidence that the true proportion of times a dime will land tails up is significantly less than the penny. O The student should reject the null hypothesis since 0.296 > 0.05. There is insufficient…

A charity institution will organize a mini outdoor concert for a cause. The estimated cost of the mini concert is P80, 000 which includes the advertising, production, talent fees and security. The organizers expect to gather a profit of P 100, 000 if all goes well. However, according to the weather report, there is 40% chance of rain on the scheduled date of the concert. If it rains, the outdoor concert will have to be canceled. What is the organizer’s expected profit?
