Answer: 0.71221

Step-by-step explanation:

We know that for binomial distribution :-

$\mu=np\ \ ;\ \sigma=\sqrt{np(1-p)}$ , where p is the proportion of success in each trial and n is the sample size.

Given : p=0.80 ; n=20

Then, $\mu=20(0.8)=16\ \ ;\ \sigma=\sqrt{20(0.8)(0.2)}=1.79$

Let X be the binomial variable.

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x=9

$z=\dfrac{9-16}{1.79}=-3.91$

For x=17

$z=\dfrac{17-16}{1.79}=0.56$

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

$P(9$

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