A study of working actors looked at age and gender. One sample of 70 male actors had a mean age of 36 and a standard deviation of 4. The other sample included 70 female actors with a mean age of 27 and a standard deviation of 5. Estimate with 99% confidence the difference between the average ages of working male (\(\mu_1\)) and female (\(\mu_2\)) actors. Round answers to the nearest hundredth. [ ] < \(\mu_1 - \mu_2\) < [ ] O A. 8.14 to 10.58
