A hotel claims that 95% of its customers are very satisfied with its service. Complete parts a through d below based on a random sample of

five customers.

a. What is the probability that exactly

four

customers are very satisfied?

b. What is the probability that more than

four

customers are very satisfied?

c. What is the probability that less than

three

customers are very satisfied?

(Round to four decimal places as needed.)

d. Suppose that of five customers selected, two responded that they are very satisfied. What conclusions can be drawn about the sample?

The probability that

2

out of

5

customers are very satisfied is

nothing,

assuming that

95%

of customers are very satisfied. Therefore, it is

likely or not likely

that randomly selecting

5

customers would result in

2

responding that they are very satisfied.

(Round to four decimal places as needed.)
