Question

A hotel claims that 90% of its customers are very satisfied with its service. Complete parts a through d below based on a random sample of eight customers. a. What is the probability that exactly seven customers are very satisfied? 0.3826 (Round to four decimal places as needed.) b. What is the probability that more than seven customers are very satisfied? 0.4305 (Round to four decimal places as needed.) c. What is the probability that less than six customers are very satisfied? (Round to four decimal places as needed.) d. Suppose that of eight customers selected, four responded that they are very satisfied. What conclusions can be drawn about the sample? The probability that 4 out of 8 customers are very satisfied is assuming that 90% of customers are very satisfied. Therefore, it is not likely that randomly selecting 8 customers would result in 4 responding that they are very satisfied. (Round to four decimal places as needed.)
