Travelers who have no intention of showing up often fail to cancel their hotel reservations in a timely manner. These travelers are known, in the parlance of the hospitality trade, as "no-shows". To protect against no-shows and late cancellations, hotels invariably overbook rooms. A recent study examined the problems of over-booking rooms in the hotel industry. The following data, extracted from the study represent the daily numbers of late cancellations and no-shows for a random sample of 10 days at a hotel:______.
18, 16, 16, 16, 14, 18, 16, 18, 14, 19.
Compute x the sample mean for the data set.

Answer:

No-shows in Hotel Reservations

Sample mean

= Sum of the samples divided by the number

= (18 + 16 + 16 + 16 + 14 + 18 + 16 + 18 + 14 + 19)/10 = 16.5

Explanation:

In mathematics and statistics, the arithmetic mean, or simply the mean or average is the sum of a collection of numbers divided by the count of numbers in the collection.

A sample mean therefore is the average of the sum of a collection of samples divided by the count of numbers in the collection.  Simply, the sample mean is the average of all the measurements in the sample.
