Question 13

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:
