Please help! Need answers by 15! This is for an exam! Proportion of US Residents Less than 25 Years Old
The US Census indicates that 35% of US residents are less than 25 years old. Figure 1 shows possible sampling distributions for the
proportion of a sample less than 25 years old, for samples of size n = 20,1 = 100, and = 500.

Figure 1 Match the dotplots with the sample size
(n) Which distribution goes with which sample size?
N = 20
N = 100
N = 500
(B) I wese a proportion based on a sample of size 20, to estimate the population parameter p=0.35, would it be very
surprising to be an estimate that is off by more than 0.10 (that is the sample proportion is less than 0,25 or greater than 045)
How about with a sample of size n=100
How about with a sample of n=500
(Repeat part bit we ask about the sample proportion being off by just 0.05 or more Would it be very surprising to get an
estimate that is off by more than 0.05?
How about with sample size n=100?
How about sample size n=500
