A study examining the number of individuals recruited by extremist organizations in New England in the past year found that, on average, the organization recruited 14.8 people with a standard deviation of 5.1. Using this information, find… (a) What proportion of organizations recruited less than 5 people? (hint: calculate z-score first!) (b) what proportion recruited more than 10 people? (c) what proportion recruited between 5 and 10 people?
