For those wondering how to find the z score, in casio 991cw u can go to distribution mode, choose inverse normal and enter the confidence interval as area (keep default values of μ and σ)

What a nice explanation...moj kar di sir ji🎉❤

at 20:21 you have not found the value of q by the formula you have written 0.95 instead of 0.05

[divinityinversace]

19:43 would it have been a problem if we took the population proportion as the claim for faulty equipment instead (so H0: P <=0.05 and H1: P > 0.05)?

[harshavardhankorlepara]

sir,
why we have taken like this in 26:38 :- P(+-)3*S.E
means why we have taken 3 ...in this problem

[lokendrakumar]

Sir your videos are very helpful, heartfelt thanks to you.

[devendersingh]

Please let me know ki one tail or two tail test kon sa lgana hai y smjh ni aata

[soyebsarkar_]

At 20:54 Q = 0.05 because Q=1-P
1-0.95= 0.05

[saivodnala]

Iam confused sometimes u took question hypothesis in null and sometimes in alternative.

[vivekmankotia]

Sir you are using which software application for writing

[hasikaKhazaaaana]

Sir in second question n=20 which is <30 then why are we using z test????

[aapnews]

Sir but since n<30 so we should be using t test right. Question at 11:39.

Koi btyega last two questions mai 3 kaise lia...Zalpha ki value ki jgh
