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 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. Whích of the following is the correct standardized test statistic and P- value for the hypotheses, H Po-Pp-0 and H, Po-Pp<0?

PART C. Records in the country show that six out of 10 convicted offenders were reconvicted 10 years after being released. Officer Chimmy, the head of a rehabilitation program at a local prison, wishes to determine if its program has been successful compared to the records in the country. He then observed a random sample of 68 convicted offenders who participated in the local ultimatearm from prison's rehabilitation program and were later released. The proportion out of these numbers who Icon made by www.flaticon.com were reconvicted 10 years after being released was recorded. Formulate the appropriate null and alternative hypotheses in symbols and words. Но: ;The of the convicted offenders who participated in the local prison's rehabilitation program who were reconvicted 10 years after being released is На: ;The of the convicted offenders who participated in the local prison's rehabilitation program who were reconvicted 10 years after being released is

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…

Please solve this question below. Thank you! 9. Challenge A bag contains 200 red and blue marbles. Three people each took samples of 25 marbles and noted the number of red marbles. Person A 17 red marbles out of 25 marbles Person B 12 red marbles out of 25 marbles Person C 20 red marbles out of 25 marbles a. Combine the samples to make one large sample. Use that sample to predict the number of red marbles in a similar bag that contains 300 marbles. b. Explain how having a fourth sample would make the estimate better.
A statistics instructor would like to know whether it is worthwhile to require students to do weekly homework assignments. For Section1 of the course, homework is assigned, collected and graded each week. In Section2, students are not required to turn in homework. At the end of the semester, the students are given the same final exam. In Section1, the numbers of students getting each grade are: 16 students got A, 22 students got B, 8 students got C, and 4 students got D. In Section2, the numbers of students getting each grade are: 8 students got A, 18 students got B, 18 students got C, and 6 students got D. Is there an association between assigning homework and exam grade? Test at the alpha = 0.05 level. a. We reject the null hypothesis with two-tailed critical values; there is an association between assigning homework and exam grade. b. We reject the null hypothesis with one-tailed critical value; there is an association between assigning homework and exam…
