Question 465006
Historically, the campus police write a ticket on 15% of the vehicles they stop on campus; violations include speeding, no valid sticker, illegal parking, etc. Student leaders will take a survey of 400 students who had been stopped by the campus police. What is the probability that 55 or more of these students have been issued a ticket? Note: Be sure to identify any assumptions or conditions needed
-----------------
Binomial Problem with n=400 and p = 0.15
---
P(55<= x <=400) = 1-binomcdf(400,0.15,54) = 0.7774
