Nine sales representatives, 6 men and 3 women, at a small company wanted to attend a national convention. There were only enough travel funds to send 3 people. The manager selected 3 people to attend and stated that the people were selected at random. The 3 people selected were women. There were concerns that no men were selected to attend the convention. 
 (a) Estimate the probability that randomly selecting 3 people from a group of 6 men and 3 women will result in selecting 3 women. (b) Based on your answer to part (a), is there reason to doubt the manager’s claim that the 3 people were selected at random? Explain. Each "resampling" will produce 100 trials.
