Let we have samples from the distribution having mean and standard deviation then according to sampling distribution of sample mean is
So if we choose large sample size n i.e. if we increase the sample size n mean is unchanged and SD is decrease i.e if then
hence mean unchanged, standard deviation decreases
Note Q22 requires additional data (sd . n)
sd(sample mean) = sd/sqrt(n)
Please rate
Same as above, the standard deviation of the sample means is equal to: a) 2.45 22....

The distribution of sample means has the same mean as the underlying population, but the standard deviation differs. Use a real world scenario to explain why it makes sense the variation decreases as the sample size increases.
If the standard deviation of a normally distributed population is 60 and we take a sample of size 25, then what is the (standard error) standard deviation of the sampling distribution of sample means. * Your answer If the mean of a population is 3 points 250 and we take a sample of size 25, then what is the mean of the sampling distribution of sample means. * Your answer 3 points A certain car model has a mean gas...
As sample sizes _____________________, the standard deviation of the sampling distribution decreases indicating that the sample means cluster more tightly around the population mean. increases change stay the same decreases
