A recent survey asked 47 randomly selected employees how long they had been employed at their current job. The mean was 4.6 years and the standard deviation was 2.3 years. What is the point estimate for the mean length of current employment? Check the requirements for constructing a confidence interval for a population proportion. Construct the 90% confidence interval for mean length of current employment. Round the results to 1 decimal place.
