Expert Solution

a. Sleep problems:

Asnwer: The scale yields a total score indicating level of insomnia with clinical cutoffs as follows: 0–7 = no clinically significant insomnia, 8–14 = sub-threshold insomnia, 15–21 = moderately severe clinical insomnia, 22–28 = severe clinical insomnia.

b. Amount of vacation

Answer: The average worker with five years of experience at a company was given 15 days of paid vacation and the average worker with 20 years of experience was given 20 paid vacation days.

c. Height

Answer: Physical characteristics of persons and objects can be measured with ratio scales, and, thus, height and weight are examples of ratio measurement. A score of 0 means there is complete absence of height or weight. A person who is 1.2 metres (4 feet) tall is two-thirds as tall as a 1.8-metre- (6-foot-) tall person.
