Question: To improve the signal-to-noise ratio (NNR) in the electrical activity of the brain, neurologists repeatedly stimulate subjects and average the responses- a procedure that assumes that signal responses are homogeneous. A study was conducted to test the homogeneous signal theory. For this study, the variance of the SNR readings of the subjects will equal 0.45, the researchers will conclude that the signals are nonhomogeneous. Signal-to-noise ratios recorded for a sample of 41 normal children ranged from .03 to 3.0. Use this information to test the theory at \(\alpha \) = .10.
