A hotel manager believes that 14% of the hotel rooms are booked. If the manager is right, what is the probability that the propo
lara [203]

Answer:

0.4996

Step-by-step explanation:

We are given;

Population proportion; p = 14% = 0.14

Sample size; n = 804

Sample proportion; p^ = 13% = 0.13

Standard deviation; σ = √np(1 - p)

σ = √(804 × 0.14 × (1 - 0.14))

σ = 9.8388

Formula for z-score is;

z = (p^ - p)/σ

z = (0.13 - 0.14)/9.8388

z = -0.01/9.8388

z = -0.001

From online z-score and probability converter attached, we have;

P(Z < -0.001) = 0.4996

The <u>correct answer</u> is:

C) Avoid using unsecured wireless networks.

Explanation:

Using an unsecured wireless network puts your information at risk.  If you use an open network, that means that absolutely anyone within range can access the same network you are on, which opens you up to potential scammers, phishers, etc.  

On the other hand, using a secured network decreases the number of people on the same network as you, since they will have to have the same password to access the network.  This helps prevent your information from falling into the wrong hands.
