9 additional students were used as a control group. Each of these students had pre and post ratings made at the same time as the pre and post ratings for the treatment group. However, the control group did not attend the lecture - slide demonstration as did the treatment group. The researcher hypothesized that improvement ( pre and post) scores for the treatment group would be higher than improvement ( pre and post) scores for the control group. What statistical...
One Management professor adopted a crossword puzzle exercise in his introductory management information systems (MIS) class, because he believes that the most important effects of engaging in a crossword exercise is the great workout it gives one’s brain—solving crossword puzzles requires several skills, such as spelling, reasoning, making inferences, evaluating choices, and drawing conclusions. That is, the exercise may enhance one’s ability to memorize words. He wants to know whether or not the crossword puzzle exercise can accelerate the learning...

stats Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor...
