QUESTION 1 Suppose we have a sample size of 100 and calculate a confidence interval. What will happen to that interval if we then get a sample size of 200 (all else equal). It will become narrower It will become wider. It will remain the same, because the mean is not changing It will get closer to 1.96.

A simple random sample of 120 vet clinics in Adelaide reveals that the vast majority of them only treat small pets (dogs, cats, rabbits, etc) and no large animals (cows, horses, etc). Of the 120 clinics sampled, 88 responded that they do not treat large animals at their clinics. If a 95% confidence interval were calculated instead of a 90% confidence interval for p, what would happen to the width of the confidence interval? Select one: a. It would be...
