Question 4

An industrial psychologist is interested in the effectiveness of an employee computer training course.A total of 7 employees are enrolled in the course.The psychologist measures computer knowledge (1)just before the training begins, (2)again at the end of training,and (3)again at a 3-month follow-up.An increase in computer knowledge from pre-training to end-of-training would suggest the training is effective.Scores on the computer knowledge test can range from 1 to 10.The tables below summarize the data and part of the data analysis:

Question 17

A biopsychologist is interested in studying the effects of marijuana on cognitive skills by studying a group of 7 rats.He puts each rat in a maze and measures the time it takes the rat (in minutes)to find the cheese at the end of the maze.He then puts a mask on the rat and has it inhale marijuana smoke for 5 seconds.He then puts the rat back in the maze,and records its time to reach the cheese.Twenty minutes later he puts the rat back in the maze to test for lasting effects of the drug.The tables below summarize the data and part of the data analysis:
