A survey of 25 randomly sampled judges employed by the state of
Florida found that they earned an average wage (including benefits)
of $67.00 per hour. The sample standard deviation was $5.75 per
hour.
- What is the best estimate of the population mean?
- Develop a 95% confidence interval for the population mean wage
(including benefits) for these employees. (Round your
answers to 2 decimal places.)
- How large a sample is needed to assess the population mean with
an allowable error of $1.00 at 98% confidence? (Round up
your answer to the next whole number.)
