Even my teacher did not explain it as well as you. A big thank sir.

[@devkumarchhatriwala4377]

This is literally the best tutorial I have seen on KZbin for hypothesis testing, I have been struggling with this topic for a while and this video helped me so much. I really appreciate all the efforts that were put into making this video. A big Thank You!

[@adityapatil4978]

hey bro at 16:38 can you pls explain me how the significance level calculated i didnt understood

[@TS6413-x6u]

23:48 Sir, for the ques on one tailed test, you mentioned that 1.80 doesn't lie between -1.64 to +1.64. So, the null hypothesis is rejected. Since it is a one tailed test, why are considering this range of -1.64 to +1.64?

[@shraddhashukla7905]

very well explained. very clear about null hypothesis. Z is playing key role. once going out of confidence is no confidence so the null hypothesis is rejected.

Please do not add meme clips between the video, may it was to make video interesting, but its actually not making it. That is making video more disturbing. It's a request.

[@shaileshdahariya9589]

Sir, p value badhane se confidence interval kam ho rha hai. 90% confidence level pe Ho: 58 is significantly equal to 60, wrong hoga. Par 95 % confidence level pe sahi hoga. Iska ye matlab hua ki confidence level badhane se hum error ki tolerance ko increase kar rhe hain. Kya meri understanding sahi hai ?

The respondent in each house was asked whether or not anyone in the house was bothered by air pollution. The responses are tabulated below (Given x2 (0.05) = 3.841) : Community Yes No Total I 43 157 200 II 81 119 200 Total 124 276 400 Can the researchers conclude that the 2 communities are bothered differently by air pollution ?
