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 \( n = 1 \).

4) "Athletes at major colleges graduated, on the whole, at virtually the same rate as other students," according to the NCAA in 1982. Suppose that in a new poll of...
