Statement I: The geometric mean of the two regression coefficients of X and Y variables gives the value of the coefficient of correlation. Statement II: If the population distribution is not normal and a sampling distribution of mean is prepared by taking small sized samples, the sampling distribution of mean is not normal.

In above explanation n indicates number of sample size . If sample size is less than 30 means small size sample and sample size is greater than 30 means large size sample. and give...

In case of a population that is not normally distributed, the sampling distributions are not normal, when n is less than 30. However, the sampling distributions approximate a norm...
