Scenario 5

A website for a small motel chain averages seven visitors every ten minutes.   Solve the probability questions for Scenario 5 by hand. (Round all probabilities to 4 decimals)

1) What is the mean number of visitors in a 3-minute period?

2) What is the probability of no visitors in a 3-minute period?

3) What is the probability of exactly one visitor in a 3-minute period?

4) What is the probability of exactly two visitors in a 3-minute period?

5) What is the probability of three or more visitors in a 3-minute period?

6) What is the expected number of visitors to the website in six minutes?

7) What is the variance of the number of expected visitors to the website in six minutes?

8) What is the standard deviation of the number of expected visitors to the website in six minutes? (Round to two decimals)
