Final answer:
The probability that someone who sleeps for more than 8 hours also sleeps for more than 10 hours is high.
Step-by-step explanation:
When analyzing sleep durations, it's crucial to consider the normal distribution of sleep patterns within a population. A majority of individuals sleep around 7-9 hours per night, with 8 hours being a commonly recommended duration for adults. Given that someone already sleeps for more than 8 hours, it indicates they are already on the higher end of the sleep duration spectrum.
Extending the sleep duration to over 10 hours is less common and often associated with specific factors such as certain health conditions, lifestyle choices, or sleep disorders. Therefore, the likelihood of someone exceeding 10 hours of sleep increases when they are already surpassing the 8-hour mark. This observation aligns with the concept that individuals with longer sleep durations tend to have an increased probability of further extending their sleep.
To illustrate, if we consider a hypothetical population where the average sleep duration is 8 hours, those who sleep more than 8 hours would likely fall into the upper percentile, making it more probable for them to surpass 10 hours. This inference is based on statistical trends in sleep duration data.
