ALICE and YouGov conducted an online poll among Americans hotel guests of more than 18 years old to understand their expectations from hotels in the year 2018-191. This poll showed that 40% of guests were interested in gaining experiences of local cuisine tastings/tours. Suppose you take a random sample of 10 hotel guests. Let, x, represent the number of guests interested in gaining experiences of local cuisine tastings/tours. Find the mean and standard deviation of x. What is the probability that x <=5? Find the probability that x > 7.

This poll showed that 40% of guests were interested in gaining experiences of local cuisine tastings/tours. Suppose you take a random sample of 10 hotel guests.
Let, x, represent the number of guests interested in gaining experiences of local cuisine tastings/tours.
- Find the
mean and standard deviation of x. - What is the
probability that x <=5? - Find the probability that x > 7.
Solution:
Let X be the number of guests interested in gaining experiences of local cuisine tastings/ tours and n be the sample number of hotel guests.
From the given information, probability that a guest interested in gaining experience of local cuisine tasting/tours is 0.40 and n=10.
