П. STA requires each student to train a rat to perform specific behaviors. Student grades are determined by the rats' performance. Mr. Simmons is concerned that students who have prior experience with training rats or other animals may have an advantage. To test the hypothesis, she gave each student a survey at the start of the class. The survey asked students about their previous animal related experiences. At the course's conclusion, she compared the rats' learning for students with prior animal experience to students without. Do the data suggest a significant difference between the two groups of students? Rat scores for students with animal Rat scores for students with no experience experience n = 15 М-66 n = 10 M= 78 SS = 1420 SS = 2030 State the hypotheses, critical values with df and alpha = .05, calculate the test statistic and show all your work for each step of the calculations, answer the question stated above in bold-italics, AND state your conclusion using the 3-sentence…
2. We want to investigate whether there exists gender bias on traffic stops by the police here in Charlotte. The Charlotte Open Data Portal includes information on different characteristics of drivers being stopped. We collected the data from 2017 and we are interested in answering the question: "Of all the drivers who are stopped, are female drivers less likely to get searched than male drivers? From the data collected we observed that 438 out of the 24,314 female drivers were searched, whercas 2,244 out of 34,095 male drivers were scarchcd. (a) that the proportion of female drivers being searched is smaller than the proportion of male drivers being searched? Is there sufficient evidence at the 0.05 significance level to conclude Construct the appropriate confidence interval for the hypothesis (b) test of part (a) and state your conclusion.
A TA in statistics thinks that the format of the conferences and the timing of the assignments may affect students' assignment marks (out of 10). He decided to design three conferences with a different format: (1) with lecturing, (2) with demonstrating problems, and (3) with involving students in active problem-solving. Twelve students attended one of the conferences (four in each format) and asked to submit their assignments at week 3. Another twelve students attended one of the conferences but asked to submit their assignments at week 5. The data are tabled below: Assignment Week 3 Week 5 Lecture 6,7,5,7 5,5,4,5 Format Demo problems 7,8,8,9 6,7,7,6 Active problems 9,10,10,10 8,9,9,10 Note: ΣΣΣx=1385 Perform the ANOVA test and table the results, stating all critical values.

A fitness course claims that it can improve an individual's physical ability. To test the effect of a physical fitness course on one's physical ability, the number of sit-ups that a person could do in one minute, both before and after the course, was recorded. Ten individuals are randomly selected to participate in the course. The results are displayed in the following table. Can it be concluded, from the data, that participation in the physical fitness course resulted in significant improvement? Let d=(number of sit-ups that can be done after taking the course)−(number of sit-ups that can be done prior to taking the course)d=(number of sit-ups that can be done after taking the course)−(number of sit-ups that can be done prior to taking the course). Use a significance level of α=0.05α=0.05 for the test. Assume that the numbers of sit-ups are normally distributed for the population both before and after taking the fitness course.

64 owners and a similar age group of pet owners. The pet owners are matched one to one with the non-pet owners for income, number of close friendships, and 0. A researcher uses a matched-subjects design to in- than singles without pets. A mood inventory survey vestigate whether single people with pets are happier happier is given to a group of 20- to 29-year-old non-p general health. The data follow: Non-Pet Owner Pet Owner Matched Pair 12 14 8. 10 13 9. 9. D 13 E 10 12 F a. Is there a significant difference in the mood scores for non-pet owners versus pet owners? Test with a = .05 for two tails. b. Construct the 95% confidence interval to estimate the size of the mean difference in mood between the population of pet owners and the population of non-pet owners. (You should find that a mean difference of p, = 0 is an acceptable value, which is consistent with the conclusion from the hypoth- esis test.) %3D D. AB
Dr. Moo conducted a research project in which she compared the impact of two types of therapy (pizza therapy and chocolate therapy) and gender on college students’ happiness. How many null hypotheses did she have, and how would you write them?
Moral judgments about a harmful behavior are expected to be associated with one’s ability to recognize how hurt the victim of the harmful behavior is. To test this a replication of the Malti and colleagues (2012) was attempted. Researchers asked 12- and 15-year-olds whether they thought it was okay to exclude a Serbian peer from going to a soccer match (1 = really not okay, 7 = really okay) and how they thought the Serbian peer would feel if he/she was not invited to the soccer match (1= very bad, 7 = very good). The results for 12 of these adolescents are below: 1. Find the correlation, r, between exclusion judgments and evaluations of the victim’s feelings (assuming the researcher wanted to use the 1 to 7 scale as a numerical interval score). Q: r= ? 2. Describe this correlation and what does this correlation indicate about the relation between exclusion judgments and evaluations of the victim’s feelings?
