The State of Virginia has instituted a series of standards of learning (SOL) tests in math, history, English, and science that all high school students must pass with a grade of 70 before they are allowed to graduate and receive their diplomas. The school superintendent of Montgomery County believes the tests are unfair because the test scores are closely related to teacher salary and tenure (i.e., the years a teacher has been at a school). The superintendent has sampled 12 other county school systems in the state and accumulated the following data for average teacher salary and average teacher tenure: a. Using Excel or QM for Windows, develop the multiple regression equation for these data. b. What is the coefficient of determination for this regression equation? Do you think the superintendent is correct in his beliefs? c. Montgomery County has an average SOL score of 74, with an average teacher salary of $27,500 and an average teacher tenure of 7.8 years. The superintendent has…
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.

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?

Among mammals, bears probably have the best sense of smell. You want to investigate this. You take food and place it in an airtight plastic container and randomly place it behind one of three panels. You repeat this 50 times. If the bear can correctly smell the food and press the panel with the food, he/she gets the food as a reward. You get the following results: Observed results Number of times the bear correctly presses the panel with food behind it: 43 Number of times the bear incorrectly presses one of the two panels without food behind it: 7 Can the bear smell the food? Give both the test statistic and the table value.

Scenario: A researcher wants to know whether a hard copy of a textbook provides additional benefits over an e-book. She conducts a study where participants are randomly assigned to read a passage either on a piece of paper or on a computer screen. After a distractor task lasting 30 minutes, the participants are tested for their comprehension of the passage with a multiple-choice test containing 10 questions about their passage. Comprehension was scored using percent correct (0 — 100%). The researcher predicts that those randomly assigned to read the passage on a piece of paper will remember significantly more than those who read the passage online. Question: What is the research / alternate hypothesis for this scenario? People who read a passage on a piece of paper will remember more than those who read a passage online. People who read a passage on a piece of paper will not remember more than those who read a passage online. Amount remembered of a passage will vary based…
