The effects of lesions in the parafascicular nucleus of 25 Norway rats (Rattus norvegicus) on running time in a straight-alley maze were investigated. The rats were randomly assigned to one of five groups, subject to the restrictions that each group contained five rats. The extent of the lesions were randomly selected and differed for each group. The following data are running times in seconds for the five groups: a) Determine if a transformation would be appropriate for this data. b) Perform an appropriate hypothesis test to determine if the extent of lesions impacted the running time in the straight-alley maze.
