Question
The average daily rate of a hotel in Canada as of August 2018 was $193.65. Assume the average daily rate follows a normal distribution with a standard deviation of $24.60.
a. What is the probability that the average daily rate of a Canadian hotel will be:
(i) less than $170
P(X < 170)=
(ii) more than $200
P(X > 200)=
(iii) Between $145 and $185
P(145 < X < 185)=
(i) less than $170
P(X < 170)=
(ii) more than $200
P(X > 200)=
(iii) Between $145 and $185
P(145 < X < 185)=
b. Determine the average daily rates that separate the:
(i) top 8% of average daily rates from the rest of the daily rates or from the bottom 92% of average daily rates
x=
(ii) bottom 15% of average daily rates from the rest of the daily rates
x=
(iii) middle 70% of average daily rates from the rest of the daily rates
= ? < x < ?
(i) top 8% of average daily rates from the rest of the daily rates or from the bottom 92% of average daily rates
x=
Round to 2 decimal places.
(ii) bottom 15% of average daily rates from the rest of the daily rates
x=
Round to 2 decimal places.
(iii) middle 70% of average daily rates from the rest of the daily rates
Round to 2 decimal places.
