Question 2 - Page 69, 70 Number of times you blink your eyes or number of breaths you take: a. In a minute b. In an hour c. In a dayThis estimation relies on measuring a small sample and scaling it up. a. In a minute Estimate: About 15-20 blinks and 12-16 breaths. Method: Count the number of times you blink or breathe in a short period, like 15 seconds, and then multiply that number by 4 to get the estimate for a full minute. b. In an hour Estimate: About 900-1,200 blinks and 700-950 breaths. Method: Take the one-minute estimate and multiply it by 60 (the number of minutes in an hour). c. In a day Estimate: About 14,000-19,000 blinks and 17,000-23,000 breaths. Method: For breaths, you multiply the hourly estimate by 24. For blinks, you would adjust the calculation, as people don't blink while sleeping. A better method is to multiply the hourly rate by the number of hours you are typically awake (e.g., 16 hours).
