1) Find the probability that among 16 randomly selected people; at least 4 believe that college is no longer a good investment.
P ( x > or = 4), n=16, p=0.1
2) Find the probability that among 16 randomly selected people; fewer than 3 believe that college is no longer a good investment.
3) Calculate the range for the "usual" number of people out of 16 who believe that college is no longer a good investment. Use m ± 2s
ANY HELP IS APPRECIATED. I started on question number 1 but not sure if I am leaning in the write direction at all. If you all could show your work so I can understand how to get the answer it would be greatly appreciated.
