A study of working actors looked at age and gender. One sample of 25 male actors had a mean age of 28 and a standard deviation of 1. The other sample included 33 female actors with a mean age of 24 and a standard deviation of 5.4. Estimate with 92% confidence the difference between the average ages of working male ( μ1 ) and female (μ2) actors. Round answers to the nearest hundredth.
