Question 651796
Travel Weekly International Air Transport Association survey asked business travelers about the purpose for their most recent business trip. 19% respond that it was for an internal company visit. Suppose 950 business travelers are randomly selected.
----
Binomial Problem with n = 950 and p(visit) = 0.19
------------------------------------------------------
Note: The numbers are quite large. Are you expected to use
a normal approximation to the binomial probabilities?
