Answer :

Final answer:

Tamara's statement indicates she had a restful night's sleep, likely including substantial periods of both NREM and REM sleep. An average cycle lasts about 90 minutes and typically includes about 25% REP time. Thus, sleeping 10 hours with half in REM may be the most accurate option.


Explanation:

Understanding Tamara's Sleep

Tamara's statement "I slept like a baby!" typically implies she enjoyed a restorative sleep experience. Scientifically, sleep cycles consist of several stages, including Non-Rapid Eye Movement (NREM) and Rapid Eye Movement (REM) sleep, each crucial for overall well-being. An adult usually has about 25% of their sleep in REM, which helps with memory consolidation and mood regulation.

In a typical night, the average adult's first sleep cycle lasts around 90 minutes, cycling through NREM stages and concluding with REM. As the night progresses, the duration of REM sleep increases, leading to more vivid dreams and restorative effects. Assuming Tamara had a full sleep cycle of about 8 hours, she likely experienced:

  • Option 1: 12 hours of sleep with about 25% in REM (3 hours)
  • Option 2: 10 hours of sleep with about 50% in REM (5 hours)
  • Option 3: 14 hours of sleep with about 50% in REM (7 hours)
  • Option 4: 16 hours of sleep with about 33% in REM (5.3 hours)

Given the average sleep architecture, if Tamara felt rested, she likely slept around 10-12 hours with a reasonable amount in REM sleep. Ultimately, saying "I slept like a baby!" suggests she enjoyed substantial periods in both NREM and REM, possibly matching closest with the option of sleeping 10 hours with one-half in REM.
