Rooms sold / total # rooms
90/115 = .78
Occupancy rate = 78%
The value of the median is going to be 6
Answer:
P(x < 92) is 0.16
Step-by-step explanation:
We are given that the normal distribution has a mean of 98 and a standard deviation of 6.
Mean =
Standard deviation = 
We are supposed to find P(x < 92)
Formula : 

Z=-1
Refer the z table for p value
So,p value = 0.1587
So, P(x < 92) is 0.16
Option A is true
Hence P(x < 92) is 0.16
