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.
