Question When people sleep, they experience various types of brain activity.Scientists have classified these types of activity into four sleep stages: 1, 2, 3, and 4 (also known as REM). Stage 3 is the only stage considered to be deep sleep. Suppose a person went to a sleep clinic to have his or her sleeping brainwaves analyzed. A technician monitored the person’s brainwaves in 15-minute intervals for 8 continuous hours and categorized them into one of the four stages. the bar graph below shows the result of the one-night study. Based on the graph, how many minutes did the patient spend in non-deep sleep over the course of the entire night? 300 Correct Incorrect Correct answer 500 Correct Incorrect Correct answer 200 Correct Incorrect Correct answer 400 Correct Incorrect Correct answer Correct Incorrect Question 6 of 10 6.
