Computer Usage and Sleep Patterns

The video tutorial explores a study on the relationship between computer use before bed and sleep duration. It explains how to interpret a frequency table, calculate total participants, and determine the number of extreme computer users. The tutorial also analyzes the association between minimal computer use and longer sleep duration, evaluating evidence through given choices.

What are the three categories of computer usage classified in the study?

• Occasional, Regular, Frequent

• Basic, Intermediate, Advanced

• Low, Medium, High

• Minimal, Moderate, Extreme

How many moderate computer users in the study slept for 5 to 7 hours?

• 34

• 10

• 17

• 25

What percentage of the total participants does the 17 moderate computer users represent?

• 20%

• 10%

• 5%

• 15%

How many extreme computer users sleep 5 to 7 hours, rounded to the nearest whole number?

• 22

• 18

• 15

• 20

What trend is observed among minimal computer users regarding sleep duration?

• They have a balanced sleep pattern.

• They tend to sleep less than 5 hours.

• They are more likely to sleep 7 or more hours.

• They sleep the same as extreme users.

What percentage of minimal computer users get 7 or more hours of sleep?

• 16%

• 33%

• 51%

• 47%

What is the percentage of people who get 7 or more hours of sleep and are minimal computer users?

• 18.3%

• 25%

• 35%

• 55%

Which group is disproportionately represented among those who get 7 or more hours of sleep?

• Extreme computer users

• Moderate computer users

• Minimal computer users

• All groups equally

What percentage of all people surveyed are minimal computer users?

• 20%

• 35%

• 50%

• 55%

Which statement supports the association between minimal computer use and more sleep?

• Moderate users have the highest sleep duration.

• Extreme users sleep more than minimal users.

• Minimal users are 35% of the total population.

• 51% of minimal users get 7 or more hours of sleep.
