Compute a 90% confidence interval for μ when n = 100 and 58.3.
However, we are also concerned about the heating issues due to high stray-
load loss. Compute a 90% upper confidence bound for μ when n = 100 and x =
58.3.
We plan to redo the assessment again. How large must n be if the width of
the 99% confidence interval for μ is to be at most 1.0?
