Question
attendance at a health club is normally distributed. the average number of people visiting the health club at any given time is 100, with a standard deviation of 48.5. the club has a capacity of 200 people.
a) what is the probability the club exceeds capacity?
b) in the past, club workers have wanted to close early on evenings before holidays when attendance was very low. the current club contract with member states that if attendance is below 5 people, the club has the option of closing early. what is the probability the club will close early?
Explanation / Answer
a- When there will be more than 200 people theclud will exceed its capacity
Z(200)=200-100/48.5=2.061
The P-Value is 0.019652 from z score table
b=Z(5)= 5-100/48.5, Z= -1.95876
The P-Value is 0.025115
