Do pets and their owners look alike? In an experiment, a statistics student provided subjects with a picture of a dogand two pictures of people. One was the owner of the dog, and the other was someone else. Sixteen of the 25subjects were able to correctly identify the owner of the dog. To determine whether this was statistically significant,the student performed a simulation of 25 coin flips where heads indicated that the participant selected the ownercorrectly by chance, and tails indicated that the participant had not. The student performed 200 such simulations,and the results are shown in the dotplot.Simulated Proportions0 2351625OOWhat is the best estimate for the P-value if a significance test is performed using the hypotheses Ho: p = 0.5 andHa: p > 0.5, where p is the true proportion of subjects like these who can correctly identify the dog's owner?21200100200:1792000.600.300.400.50Sample proportion of correct identifications0.70

Gallup conducted a survey of 1,015 randomly selected U.S. adults about "Black Friday" shopping. They asked the following question: "As you know, the Friday after Thanksgiving is one of the biggest shopping days of the year. Looking ahead, do you personally plan on shopping on the Friday after Thanksgiving, or not?" Of the 515 men who responded, 16% said "Yes." Of the 500 women who responded, 20% said "Yes." The standard error of the differences in proportions (PM - Pw) is about SE = 0.025. Use the normal distribution to test, at the 5% level, if the proportions of men and women who planned to shop on the Friday after Thanksgiving are significantly different. The sample size is large enough to use the normal distribution. Z= i p-value = i There is ✓evidence that the proportion of men and women who planned to shop the Friday after Thanksgiving are significantly different.

A researcher wants to see if police officers’ enthusiasm for their jobs changes after having endured a horrific event (such as killing someone or being shot). She tests a group of officers who have endured such an event and another group that has not on a measure of job satisfaction. What test should she run? Is it one-tailed or two-tailed test?
A group of 50,000 tax forms has an average gross income of $37,000, with an SD of about $20,000. Furthermore, 20% of the forms have a gross income over $50,000. A group of 900 forms is chosen at random for audit. What is the chance that between 19% and 21% of the forms chosen for audit have gross income over $50,000?

cording to a job website, each job opening on average attracted 251 résumés in 2016. The job market improved in 2017 compared to 2016, which means that more people will likely be switching jobs but also fewer nemploved workers remain in the job market. To find out which trend is stronger, a random sample of 20 employers in a region was taken. Each employer reported how many résumés they received in 2017 for each b opening. Their answers are shown in the accompanying table. Using a = 0.10, complete parts a through d. Click the icon to view the data on résumés received, a. State the null and alternative hypotheses.

Question: One large course has 900 students, broken down into section meetings with 30 students each. The section meetings are led by GSI’s. On the final, the class average is 64, and the SD is 20. However, in one section the average is only 55. The GSI argues that: “If you took 30 students at random from the class, there is a pretty good chance they would average below 55 on the final. That’s what happened to me, and my teaching was as good as the other GSI’s” Is this a good defense? Answer yes or no and justify your answer.

Does the location of your seat in a classroom play a role in attendance or grade? 1600 students in a physics course were randomly assigned to one of four groups. The 400 students in group 1 sat 0 to 4 meters from the front of the class, the 400 students in group 2 sat 4 to 6.5 meters from the front, the 400 students in group 3 sat 6.5 to 9 meters from the front, and the 400 students in group 4 sat 9 to 12 meters from the front. Complete parts (a) through (c). Click the icon to view the chi-square table of critical values. (a) For the first half of the semester, the attendance for the whole class averaged 83%. So, if there is no effect due to seat location, we would expect 83% of students in each group to attend. The data show the attendance history for each group. How many students in each group attended, on average? Is there a significant difference among the groups in attendance patterns? 3 4 Group Attendance 1 0.84 0.84 0.84 0.80 The number of students who attended in the first…

A crossover trial is a type of experiment used to compare two drugs. Subjects take one drug for a period of time, then switch to the other. The responses of the subjects are then compared using matched-pair methods. In an experiment to compare two pain relievers, seven subjects took one pain reliever for two weeks, then switched to the other. They rated their pain level from 1 to 10, with larger numbers representing higher levels of pain. The results were: Subject Drug A Drug B 1 6 5 2 3 1 3 4 4 7 6 2 7 4 2 Can you conclude that the mean pain level is less with drug B? Use a=0.05. (1) Critical Value (Round off to 3 decimal places): (2) Test Statistic (Round off to 2 decimal places): (3) Conclusion: (Type 'Reject HO' or 'Fail to Reject HO')
