Confidence intervals and Hypothesis Testing (Q table and Student's T table are at the end of the exam) a) Consider collecting a sample of 9 random independent values from a population with Gaussian distribution whose mean is 100 and variance is 25. Determine the 90-percent confidence interval for the sample mean. b) Repeat part (a) with the assumption that the population variance is unknown; but assume that you do not know the population variance. You can also assume that you have determined that the unbiased estimate of the variance is 25 for your sample.
