You Conduct a Single Sample Experiment to Determine If the Cingulate

You conduct a single sample experiment to determine if the cingulate cortex is involved in learning tasks involving choice behavior. Twenty-two rats with lesions of the cingulate cortex are tested in a two choice Y-maze with the correct arm of the maze being randomly determined from trial-to-trial. A signal light illuminates the correct arm on each trial. Assume that cingulate cortex lesions do not interfere with reception of the signal light. Previous research with a large number of rats on this task has shown that the mean number of trials learn the task is 15 trials. The results of the experiment show a mean of 18 trials with a standard deviation of 5.8 for the lesioned rats to learn the task.
