Paulo is creating a confidence interval based on sample data for the percentage of Americans that own a dog. His work is shown below.
for some reason it won't let me add in the picture as an attachment or as anything. Basically its like this- E = 1.645 • .452(1-.452)/950
And then all of the .452 etc is in a little square root thing.
Based on Paulo’s work, what conclusion can be drawn from the sample data he collected?
Complete the statement to form the conclusion.
It can be said with
90% confidence that between 42.5% and 47.9% of Americans own a dog.
90% confidence that between 45.2% and 54.8% of Americans own a dog.
95% confidence that between 42.5% and 47.9% of Americans own a dog.
95% confidence that between 45.2% and 54.8% of Americans own a dog.
The answer is (A) but if someone wants to explain why it is (A) that would be awesome
