One concept I found interesting from Chapter 7 on hypothesis testing is the p-value and how it helps us make decisions in statistics. I found a really helpful video from The organic Chemistry tutor that explains p-values in a simple way: https://youtu.be/zJ8e_wAWUzE?si=ZadkqyJJlx7xnfm1 The video explains that a p-value is a number that helps us see how likely it is to get our results if the original assumption (the "null hypothesis") is true. If the p-value is very low, it means our results are pretty surprising, which might mean the null hypothesis isn't true. This video helped me understand that when the p-value is less than a certain threshold (like 0.05), it means we have enough evidence to think that something interesting is going on and might reject the null hypothesis. The visuals and examples made it a lot easier to see how p-values help in making decisions
