Talent, Ltd., a Hollywood casting company, is selecting a group of extras for a movie. The ages of the first 20 men to be interviewed are 55 49 52 57 56 57 61 60 51 50 54 59 49 56 55 56 59 62 52 54 The director of the movie wants men whose ages are fairly tightly grouped around 55 years. Being a statistics buff of sorts, the director suggests that a standard deviation of 3 years would be acceptable. Does this group of extras qualify? Discuss
