Sir, please give clarity on how was the Null Hypothesis assumed?
Thanku so much for clearing my doubt... It was so helpful for my exams,, thankkuu so much
sir what if we assumed the null hypothesis that quinine is effective...what will be difference in calculation??
for the X2 goodness of fit test: what if you had 3 replicates for each variable (say i have variables a, b, c, d and 3 replicate values for each (eg variable a has values 0.1, 0.2, 0.3) can I do the chi squared test on the 4 variables? Do I have to find the mean of each variable then do the chi squared test? or is there a better test for that? Thanks!
Really , helpful .... Thank you sir .
Sir this video is really helpful. But i am unable to understamd what to test to apply in different questions. Pls help me sir i have exam of Phd cource work.

Excellent information sir thanks
Thank you sir, its helps to do for my research work

Chocolate of 250g produced in a factory were observed to have standard deviation of 2g. A random sample of 20 chocolates showed a standard deviations of 1.5g. What is chi value for the sample?? a) 7.2 b.) 6 c.) 12 d) 33.3 Please solve it
How do we assume hypothesis ,why don't we assume H⁰ as quinine effective in malaria,???
Sir I have a question what will we do if their is any less than 5 value or 0 in the table how can we do that
Thank a lot sir ❤
Very helpful sir🙏🙏👍👍👍
Sir, if the Null hypothesis was assumed as "Quinin is effective in checking Malaria" in that case with the above calculation that would have been failed and rejected. So conclusion would have been "Quinin is NOT effective in checking Malaria". Will that also be right?

Why we take null hypothesis as not effective?
What if we take H°= effective in checking malaria After the calculation the answer will be same like null hypothesis will be rejected then it will not effective. How is this ambiguity in this question? Plz explain sir
Very helpful😀
very nice sir 🙏
Thanx for the example, thro Minitab evaluated P = 0.03, since P < Alpha which is 0.05 , we reject the Null Hypothesis ...

Why we took Quinone as non effective?

Best ever
are we not considering whether the test is a two tailed test and divide the level of significance by two? or this is not considered in this kind of test?
