The city wishes to estimate the average commute distance for all city employees. They collect a random sample of 68 employees and find a sample mean of \( \bar{x}=10.6 \) miles. They also assume a population standard deviation of \( \sigma=1.1 \) miles. Calculate the \( z \) interval to estimate, \( \boldsymbol{\mu} \), the average commute distance for all city employees with \( 95 \% \) confidence.
Round your answers to 2 decimal places.
Find the Critical Value \( z^{*} \) : \( \square \)
Point Estimate: \( \square \)
Margin of Error: \( \square \)
Write the interval as (lower bound, upper bound)
\( \square \)
\( \square \)
