3. 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. c) Count the number of measurements that actually fall within the interval(-28, +2s) and express the interval count as a percentage of total number of measurements. at least 75% 100% 68% 95%
1. Measure your height and find how many standard deviations you are from 50th percentile using the Anthropometry table in slide 17 in the Anthropometry slides. My height is 5 feet 7 inches. 2. Using this measured stature, estimate the lengths of your forearm, foot, and hand (https://exrx.net/Kinesiology/Segments). 3. Measure your forearm, foot, and hand using a tape measure (or some other device).( forearm= 7inches; foot=10inches; hand=22inches). 4. Indicate the error in %s for each segment (compare measured vs table value), and indicate which if your 3 segments was the furthest off.
