Question
For a data set obtained from a sample of size \( n = 64 \) with \( \bar{x} = 44.25 \), it is known that \( \sigma = 5.5 \). (a) What is the point estimate of \( \mu \)? \[ \mu = \, \boxed{} \] (b) Find \( z \) score corresponding to a 95% confidence level, \( z_{\alpha/2} \). Recall that \( (1 - \alpha)100\% = 95\%\). Give your answer with two decimal places. \[ z = \, \boxed{} \] (c) Construct a 95% confidence interval for \( \mu \). Round the answers to four decimal places. \[ \boxed{} < \mu < \boxed{} \] (d) What is the margin of error in part (c)? Round the answer to four decimal places. \[ E = \, \boxed{} \]
