I have a question, nowthat CLM holds when n > 30, why it is possible to apply CLM when 4 cats are chosen in your question?

to apply CLT sample size should be greater or equal to 30 but in your example you have taken sample size of 4

There are four samples and each sample contains more than 30 element
@praveenchandrasrivastava6557 Жыл бұрын
@@abhaynishesh so the sample size is more than 30 right? and so we should divide the population mean with root of sample size and not by the root of number of samples.

@@praveenchandrasrivastava6557 Yes Each sample has greater than 30 elements ( here more than 30 students whose height and weight are being taken),. And finding Z value he divided population standard deviation by root of no of samples

In example sample size is 4 , then how apply CLT

Why subtracting 0.5 from z value, sir please explain
@nskshivakumar2257 Жыл бұрын
It is not necessarily sir mistake
@indranigogoi519010 ай бұрын
since it's a two tail test, we must take the half of the z value.

@DigitalELearning8 ай бұрын
In normal distribution numerical questions, we sometimes subtract 0.5 from the z-value for two main reasons: 1. Continuity Correction :Subtracting 0.5 accounts for the fact that the probability of a specific value (like 2.5) is actually the probability between 2 and 3. 2) Area calculation for "less than or equal to" situations: Since we only want the probability greater than the z-value, we subtract 0.5 to account for the area already included in the table (below the z-value).

what if the last line of questions says find the probablity that weight lies between so and so..then what will we do with the Zvalues??plz answer coz tomorrow is my exam
@DigitalELearning8 ай бұрын
If the question asks for the probability that the weight lies between certain values, you find the Z-values for those values and then find the probability using the Z-table or calculator. The process is similar, just with different Z-values. Always make sure to check whether the Z-table or calculator provides probabilities for the specific range you're interested in.

Why 30?
@DigitalELearning19 күн бұрын
The "30 samples" rule in the context of the Central Limit Theorem (CLT) is a guideline suggesting that a sample size of 30 is often sufficient for the sampling distribution of the sample mean to be approximately normally distributed.
