Question 286508
An accounting professor claims that one quarter of undergraduate business students major in accounting. If we assume this is true, what is the probability that in a random sample of 790 undergraduate business students, 179 or more will major in accounting? 
-----------------------------
Binomial Problem with n = 790 ; p = 0.25
---
P(179 <= x <= 790) 
= 1- P(0<= x <=178)
= 1 - binomcdf(790,0.25,178) 
= 0.94198...
