If a random sample of 10 people found that 9 were pro-life (i.e., 90%), while another random sample
of 1000 people from the same population found that 550 were pro-life (i.e. 55%), which would you find to be more significant? Why?

you like the pollster to provide?
Thanks for letting me work on your question. Here is my explanation:
Q1: to be more significant, the sample size needs to be ...
The solution provides a detailed explanation as to how to find margin of error and compare significance level.
