b) Find a function of \( \overline{Y} \) that is an unbiased estimator of \( \theta \).
3) Suppose that the random variable \( Y \) is an observation from a normal distribution with unknown mean \( \mu \) and variance 1. Find a 95% confidence interval for \( \mu \).
comment: Use the CI for \( \mu \) when \( \sigma \) is known and \( n = 1 \).
