Question 2 1 pts Consider random sample W], . . ., W20o with E[Wi] = *. We are willing to assume that W- ~ N(0, 1). We observe one realization of the random sample for which the realized average is * = 13 and the realized value of estimator $ is s = 4. Based on that realization and knowing that 20.10 = 1.28 20.05 = 1.64. 20.025 = 1.96. 20.01 = 2.33, and . Zo.005 = 2.58. what is the 90% confidence interval for u"? [12.54, 13.46] O [12.64, 13.36] [12.45, 13.55] [12.34, 13.66]
