Q2: The electrical resistances of components are measured as they are produced. A sample of six items gives a sample mean of 2.62 ohms and a sample standard deviation of 0.121 ohms. At what observed level of significance is this sample mean significantly different from a population mean of 2.80 ohms? Is there less than 2% probability of getting a sample mean this far away from 2.80 ohms or farther purely by chance when the population mean is 2.80 ohms?
