- 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?Jason scored a 83% out of 100 and his perantile rank was 12 Rogns scored a 85% out of 100 his car percentile rank and was 75 out of Sam Scond 80% out of 100 and hur percentile rank was 70 who perform the best.?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…
