In a study to establish the absolute threshold of hearing, 80 male college freshmen were each seated in a soundproof room and a 150 H tone was presented at a large number of stimulus levels in a randomized order. The student was asked to press a button if he detected the tone; the experimenter recorded the lowest stimulus level at which the tone was detected. The mean for the group was 22.2 dB with s = 2.1. Estimate the mean absolute threshold for all college freshmen. dB Calculate the 95% margin of error (in dB). (Round your answer to two decimal places.) dB
