Thanks 😊👍🏻😊👍🏻😊👍🏻 Jai Shree Ram

shouldn't we perform a t test here as the sample size is less than 30 so the CLT does not kick in.

Sir if don't know anything about population how we can derive to the standard deviation?

finally

Which software is he using for notes

🙏🙏🔥

Sir ek doubt hai sir jab hame population ka standard deviations nahi pata tho kya kare like exit poll? And tab kaise find out kare c.i because formula me population standard deviations hai

for 80% CI with same question the decision boundary is between -1.28 to +1.28 significance value is 0.05 lower CI = 519.9 and upper CI = 520.1 i am not 100% sure but if i am right then sir plz reply plz

why are we not performing t test here?

They is no tutorial videos like this in my language

Nice session😊❤

In previous video about hypothesis testing, you said that "If sample size is less than 30 we use t-test". In example of this video sample size = 25 but you used Z-sore from Z table to find the Confidence Interval, why not t table?. Am I missing any point?
