Question 856212: Hello, I really need some help with my statistics homework! Here is the data:
Rooms: 230 Overbooking: 10%(230+23=253) Data reveals there is a 12% chance no show rate except when there is a conference. When there is a conference conducted the no show rate drops to 5%. Now here is the question:
1) What is the probability of more than 230 guests showing up at the 12% no show rate when 253 reservations are made?
I have tried to work this out in a spreadsheet, but I don't know how to find the 12% no show rate or the 5% no show rate and I get stuck on the rest of the problem after that, thank you!

You can put this solution on YOUR website! 1) What is the probability of more than 230 guests showing up at the 12% no show rate when 253 reservations are made?
----
binomial problem with n = 253 and p(show = 0.88
--------
P(231<= x <= 253) = 1 - binomcdf(253,0.88,230) = 0.0595
