###### Question:

98/files/folder/ stpreview- 650874 df the biological basis of memory. Using rodents as a model to study memory processes, you are attempting to demonstrate that memories represent a physical change in the brain and that memories for certain skills can be learned" by having naive rats eat the brains of rats that had learned how to perform a task perfectly. Thus you have two groups of rats: one group has never learned how to run through the maze (nalve rats) and the second group (experienced group) can run through the maze perfectly because of extensive training prior to having their brains removed. You intend on feeding the fresh brains tissue to the naive group of rats (tacos con seso de ratóe) and subsequently measuring their maze running ability. Prior to consuming the brain tissue, you place the naive rats in the maze and record the time it takes each rat to reach the end of the maze. After one trail through the maze, you then feed the brain tissue of the to and record the time to completion in seconds for each rat just as you had done previously experienced rats to your naive rats (N 10) and place them back in the maze maze running times are listed below; use the data to answer the following questions. Choose the appropriate inferential test to analyze your data, be sure to include descriptive statistics, any relevant graphs, and measures of effect size and the percent of variability accounted for by your manipulation. The choice of which descriptive and inferential tests to use is up to you, but as with most studies you need to perform the appropriate tests and only the tests which are most relevant (ie. don't calculate all possible statistics to ensure that you have the correct ones unnecessary or incorrect choices will have a negative impact on your grade.) Maze completion time in seconds Subject Before eating brains After eating brains (naive rat)(Seconds 42 36 45 39 35 30 59 75 10 52 What is Ho What is H. What is the independent variable? What is the dependent variable?
