New York City is the most expensive city in the United States for lodging. The room rate is $204 per night (USA Today, April 30,

Arisa [49]

Answer:

a. P=0.35

b. P=0.12

c. P=0.49

d. Cost: more than $249 per night.

Step-by-step explanation:

We assume a normal distribution with mean $204 and s.d of $55.

To calculate the probability we calculate the z-value for each case

a. What is the probability that a hotel room costs $225 or more

$z=\frac{X-\mu}{\sigma}=\frac{225-204}{55}= \frac{21}{55}= 0.382\\\\P(X>225)=P(z>0.382)=0.35$

b. What is the probability that a hotel room costs less than $140

$z=\frac{140-204}{55}= \frac{-64}{55}=-1.164\\\\P(X$

c. What is the probability that a hotel room costs between $200 and $300

$z=\frac{200-204}{55}= \frac{-4}{55}=-0.073\\\\P(X$

d. What is the cost of the most expensive 20% of hotel rooms in New York City?

In this case, we have to estimate z' so thats P(z>z')=0.2. This value is z=0.841.

Then, the value of X should be:

$X=\mu+z*\sigma=204+0.815*55=204+45=249$
