Thank you I'm glad I came across this video the other ones are kinda too complex for a 7th grader I just need a simple meaning for the Null and Alternative Hypothesis for my homework thank you again ❤
NO - when you talk about null- it says null hypothesis sign should have = , greater tha = and less than = - in this expamples he has mentioned greate than = so its correct
Two problems: first, and more serious, the null hypotheses should be ⩽, not =. These are not equality hypotheses. (That is, they are one-tailed, not two-tailed.) Second, the multiple choice options A and B are simply irrelevant. Only C and D are plausible answers.
Chitu Okoli A coffee dispenser claiming to dispense 530mL coffee SHOULD dispense exactly that amount, not more not even less. So the null hypothesis is indeed an equality hypothesis.
@@tahrimamohsin976 : The video is mistaken in mixing an equality null hypothesis with an inequality alternative hypothesis. Either both should be equality or both should be inequality; you cannot mix the two. Here is what the video shows: H0 : μ = 530 mL Ha : μ >/< 530 ml This is wrong no matter how you look at it. Only one of the following is valid: H0 : μ = 530 mL Ha : μ ≠ 530 ml H0 : μ ≤ 530 mL Ha : μ > 530 ml H0 : μ ≥ 530 mL Ha : μ < 530 ml I hope my point is clearer now.
@@tahrimamohsin976 : By comparison, the second example about sleep correctly matches inequality hypotheses. The mistake is only in the first example on coffee dispensing.
@@ChituOkoli I agree with you. But this is just a formality, the calculation is the same. He was teaching, his point was to simply explain what the null hypothesis means or is.
Very well explained. Thank you!

Really really informative. thank you for your effort and explanation.
Am I watching this video while taking Algebra II Honors, and I don’t plan to take AP Statistics? That’s some great help!
Ap bio here
4:15 we usually teach that the null has to involve equality, so mu=8.

Thank you xx
Good presentation sir
Thanku soo much
very very nice stats practice here!

If there's a coffee dispenser that CLAIMS to dispense EXACTLY 530 milliliters then the null hypothesis should be an EQUALITY hypothesis you idiot.

Last!!! Awww
Gus Fring
wait i thought the signs had to compliment each other
I love You!
first haha
Second
