Augmenting-reducing and sensation seeking: a test of Sales' hypothesis
Abstract:
Physiologically, augmenters amplify incoming stimulation, while reducers attenuate such stimulation. Sales has theorized that this characteristic is a determinant of an individual's need for stimulation and that reducers require more actual stimulation to reach this perceived optimal level than do augmenters. The theory predicts that measures of these characteristics would be correlated. The absolute auditory threshold was used as a measure of augmenting-reducing and the Sensation-Seeking Scale as a measure of need for stimulation in a study that tested 42 college students. The theoretical prediction was not confirmed. The bearing of these negative findings upon Sales' theory and the possibility that the auditory threshold is not a valid measure of augmenting-reducing were discussed.

Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...
