Tutorial 18-Hypothesis Testing And Statistical Analysis Using T Test

[@mahalaxmiindapure8961]

for Confidence Interval = 80 , Answer ----decision boundary between -1.311 and + 1.311, t-score= 10.96 therefore we reject null hypothesis

[@ketanverma7839]

Got the same

[@RamaKrishna-ll8iz]

Acceptance range will be - 1.311 to 1.311 T value will be same as 10.96. So Reject the null hypothesis

[@samarthyadav4274]

Same

Thanks krish for such a valuable tutorial. It's my humble Request to improve the hand writing and would be great if you share notes in pdf format as well.

[@sumitkoshti1171]

Mue = 100 X = 140 n = 30 CI = 80% Sample standard deviation s = 20 1. Hypothesis H0 : Mue equal to 100, H1 : Mue not equal to 100 2. Let's find significance value alfa, alfa = 1-CI alfa= 1-0.8 alfa = 0.2 or 20% 3. Let's find decision boundary, as it's two tailed test, Alfa = 0.2 And degree of Freedom = n-1 = 30-1 = 29 So, For Alfa = 0.2 and Dof = 29 the Decision boundary from T able is +-1.311 Decision Rule : If T-test value is less than -1.311 or greater than +1.311 then we reject the null hypothesis. 4. Now calculate T test value T = X-mue/s/under root n T = 10.95 5. Conclusion : As t-test value 10.95 is greater than 1.311, We reject the null hypothesis which means that medication gives us positive impact and helps to gain intelligence.

Amazing sir g love u

[@iqrajannat]

sir completed with the playlist, waiting for more videos, thanksyou for putting efforts for us

[@hardsoul00]

LOVE U SIR G

[@ashishvinod2193]

please continue the statistics playlist sir.because Placements are near.

[@alphapoint389]

Sir how formulas are derived?

[@shashankbadoni6694]

range is from -1.311 to 1.311 , t = 10.96 hence we reject the null hypothesis and the result of medicine is +ve on the people.

[@MovieOk-p8q]

Please complete playlist

[@akhilrana07]

acceptance range will be (-1.311) to (+1.311) T test value will be the same as the first example so, we reject the null hypothesis

[@Bharatverse308]

So Z test me degree of freedom use nhj hota? Right

Sir plz provide the pdf notes also

[@sunilkushwaha5642]

Krish ji next tutorial kab tk aayegi . Kuch update ?

[@farhanharoon6546]

I have a question: Why are we rejecting the Null hypothesis? The population mean is for those people who have not taken the medication (which is True) and the new mean is for those people who have taken the medication (which is not related to the population mean). In any case, if participants of the sample take a medication, their mean may or may not differ from the population mean but why does that negate the Null hypothesis? Please help me with this doubt?

[@farhanharoon6546]

Should'nt the null hypothesis be: "The medication has no efect on IQ"?

[@altmash7872]

sir mera CI 0.2 araha hyen T table me kya ho ga

[@BhagwatGeeta_s]

sir please completed this tutorial i am waiting for your next videos

[@vaibhav1757]

sir please upload videos on further topics, i have exams in the end of this month plzz . ITS A REQUEST

[@kdasurrenderedsoul7613]

Hare Krishna 😊

[@anshukaurav2896]

if sample size =>30 then we used z-test , if

[@prateekpal2249]

the standard deviation given was for the sample not for the population so we could have directly used it instead of dividing it by sqrt(n). Can anyone please explain??

[@ashishvinod2193]

T table value = 1.311 and our T test calculated value remains as it is 10.96.. T test calculated value > t table value so reject the null hypothesis and this medicine increase the IQ people..

[@sauravjha1714]

Try to make video without the two tail test case!!! It will be helpful!

[@DiVi-v1p]

we will reject the null hypothesis because acceptance area for CI=80% is 1.31

[@Kiranputraakash138]

Sir please upload new lecture

[@rohitrohit6883]

according to me if C.I. = 80% then our conclusion Reject Null Hypothesis. (t value=10.96) which is greater than boundary value i.e , +1.311

[@DuraidKhalid]

decision boundary is coming 1.645 to right and -1.645 to left and t value is same as before so we should reject null hypothesis

[@fenisha-hb6yf]

well the simplicity of teaching method is commendable!!🤌🤌🤌

[@soumyabrata111]

wow
