(1.) A normal population has a mean of  µ = 100. A sample of n = 36 is selected from the population, and a treatment is administered to the sample. After treatment, the sample mean is computed to be M = 106. Assuming that the population standard deviation is σ = 12, use the data to test whether or not the treatment has a significant effect. Use a one tailed test. Hypothesis: Zcrit= z test calculation: Conclusion: (2.) A mood questionnaire...
