Explanation / Answer

Q 4) True

Becouse varience of sampling distribution of mean is (varience/sample size)

Hence spread of sampling distribution of mean is 1/n times the spread of population.

Q 5) True

Becouse sample size is very large hence one can assume normal distribution.

When sample size large enough then we can assume normal distribution to the data.
