Rescaled RV and their CDF: normal distribution Question: Assume  that  20%  of  adult  population  in  a  given  province  have  a  college  degree, and  suppose  we  have  a  random  sample  of  1500  adults. What  is  a  probability  that  more  than  350  people  in  the  sample  have  a  college degree? Find  such  q   so  the  number  of  people  with  a  college  degree  in  our  random  sample exceeds  q   with  probability  95%.
