Research question: Do adult learners and traditional students score differently on the midterm exam? Midterm exam scores were collected from a sample of 200 students. In that sample, 120 identified as adults learners and 80 identified as traditional students. Which of the following statistical procedures can be used to address this research question using these data?
Paired (dependent) means t test
One sample mean t test
Two independent means t test
One sample proportion z test
Homework Answers
For the above experiment, Two independent means t-test is used among all 4.
Because the samples are not related to each other, in a way that the scores from one sample(Adult learners) are unrelated from the scores of another sample(Traditional Students).

Research question: Amongst all Penn State students, do traditional-age students and adult learners differ in terms of their grade point averages (GPA)? Researchers are going to collect data from 1,000 Penn State students. They will call each student to ask whether they identify as a traditional-age student or as an adult learner. They will also ask each student for their GPA (scale of 0 to 4.0). 1) If a difference is found in this study, can the researchers conclude that...

Do students reduce study time in classes where they achieve a higher midterm score? In a Journal of Economic Education article (Winter 2005), Gregory Krohn and Catherine O'Connor studied student effort and performance in a class over a semester. In an intermediate macroeconomics course, they found that "students respond to higher midterm scores by reducing the number of hours they subsequently allocate to studying for the course." Suppose that a random sample of n = 8 students who performed well...

A psychologist believes that students' test scores will be affected if they have too much caffeine before taking an exam. To examine this, she has a sample of n= 15 students drink five cups of coffee before taking an exam. She uses an exam that has a population mean of μ=72 and a population standard deviation of σ = 3. The mean test score for the sample of 15 students who drank five cups of coffee before taking the exam...

2. In a large class, an in-person exam, where the lazy students couldn't do cheating, in a random sample of 8 lazy students, average exam score was 42.6 with sample standard deviation 4.4, while in a random sample of 10 non-lazy students, the average exam score was 49.8 with sample standard deviation 3.1. Assume that the two populations (Exam scores for the students who do not cheat) are normally distributed. Exam was out of 60points. (a) Assume that the two...
