A Gallup Poll in 1997 asked What do you think is the ideal number of children for a family to have? In a random sample of 1000 Americans, aged 18 or older, 50 responded that having 0 to 2 children was ideal. What is the conservative margin of error for this sample?

Answer to Question 2

A Type 1 error is to mistakenly decide on a guilty verdict when the defendant is truly innocent. The Type 2 error is to mistakenly decide on a not guilty verdict when the defendant is truly guilty.
