Student Absences and Grades on the Final Exam Dr. V. noticed that the more frequently a student is late or absent from class the worse he or she performs on the final exam. He decided to investigate. Dr. V. collected a random sample of 22 students. This sample includes the number of times a student is absent and their grades on the final exam. The data can be found in the Excel file Assignment10.xlsx. Do not use any software that I did not assign. Question 1: Which or the two variables (times absent or grades on the final exam) is the independent variable and which is the dependent variable?

Dataset: NES. Variables: spend8, nesw.) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the Analyze ▶ Compare Means ▶ One-Sample T Test procedure. You then will draw inferences about the population mean. Make sure you weight observations using the nesw variable so your results are nationally representative. A. The spend8 variable has a sample mean of ______.

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…
