Choosing the right laptop

You're choosing between two laptop models for your data projects. Both need strong battery life so you can work from anywhere without running out of charge.

Model A averages 13 hours, and Model B averages 12 hours of battery life, based on real-world testing.

To find the more reliable option, you ask your AI assistant for the confidence and prediction intervals of each model’s battery life.

Since you need to be sure your laptop's battery life is reliable and doesn't fluctuate too much, which model is the better choice?
