2. Random sample of students is selected. Even though the sampling is random the probability of proper distribution can not be guaranteed. Thus, there is bias is sampling methodology.
3
As sample size increases standard deviation decreases and vice versa. Thus, the spread will be more when sample size is less and narrower when sample size is large.
Thus, sample size for A > sample size for B
