2. The output voltage for an electric circuit is specified to be 130. A sample of 40 independent -, readings on the voltage for this circuit gave a sample mean 128.6 and standard deviation 2.1. (a) Test the hypothesis that the average output voltage is 130 against the alternative that it is less than 130. Use a test with level .05. Report the p-value as well. (b) Determine B of the test above for alternate hypothesis Ha: u = 129.
