Question 375517: An investigator chooses 5 rats random from the colony of rats maintained by the psychology department of the university. After special training to delay response, the reaction times in tenths of seconds to a signal were recorded and found to be �5, 3, 6, 4, 10�. Test the hypothesis that the mean reaction time for rats of this type is 4 tenths of a second.

Hi,

*Note: Formula for the test statistic is 

In this case n = 5

Entering the Data into an Excel worksheet column and applying the Data Analysis tool

found  and  for this sampling.

 = -.02/.086 = -.2326

P(t < -.2326) = .4080 Or 40.80%

The test results would show that this sampling is well within the average

of mu = .4sec
