Apsychological experiment was conducted to investigate the length of time (time delay) between the administration of a stimulus and the observation of a specified reaction. a random sample of 36 persons was subjected to the stimulus, and the time delay was recorded. the sample mean and standard deviation were 2.2 and .57 seconds, respectively. is there significant evidence that the mean time delay for the hypothetical population of all persons who may be subjected to the stimulus differs from 1.6 seconds? use a  .05. what is the level of significance of the test?
