Guided Notes
Key concepts students will learn:
- •
The null hypothesis assumes things are happening as expected, often with a statement of equality, while the alternative hypothesis claims there is a difference or new news.
- •
In the first example, the null hypothesis is that the mean amount of drink dispensed is 530 milliliters, and the alternative hypothesis is that it is greater than 530 milliliters.
- •
In the second example, the null hypothesis is that students get at least eight hours of sleep, while the alternative hypothesis is that students get less than eight hours of sleep on average.
