Alternative Hypothesis is what you want to prove.

In the video: the mean salary is >=$125,000 (Ho) and u want to prove that it is < $125,000 (H1)

first quiz question: you want to prove your height is above average >>>> Ho is height <= average and H1 is height >average ( what you want to prove)

Thanks for your explanation, but it's still a bit difficul de defin H0 and H1

H0 > the fact you want to reject, H1 > the fact you want to approve. Is it like this?

For example, someone says me that the average women height is 1.65 cm. And I want to prove that the average height for women is lower than that.

So, my H0 is average women height is >= 1.65 cm, and my H1 is average women height is < 1.65 cm. Is my understanding correct here?
