, where p is the proportion of success in each trial and n is the sample size.
Given : p=0.80 ; n=20
Then, 
Let X be the binomial variable.
z-score : 
For x=9

For x=17

Then, the probability that more than 9 but less than 17 of the hotels in the sample is given by :-

Hence, the probability that more than 9 but less than 17 of the hotels in the sample = 0.71221
