A hotel claims that

85%

of its customers are very satisfied with its service. Complete parts a through d below based on a random sample of

seven

customers.

a. What is the probability that exactly

six

customers are very satisfied?

nothing

(Round to four decimal places as needed.)

b. What is the probability that more than

six

customers are very satisfied?

nothing

(Round to four decimal places as needed.)

c. What is the probability that less than

five

customers are very satisfied?

nothing

(Round to four decimal places as needed.)

d. Suppose that of

seven

customers selected,

three

responded that they are very satisfied. What conclusions can be drawn about the sample?

The probability that

3

out of

7

customers are very satisfied is

nothing,

assuming that

85%

of customers are very satisfied. Therefore, it is

likely

not likely

that randomly selecting

7

customers would result in

3

responding that they are very satisfied.
