There was a question on the exam about trying to figure out the sample size given a confudence interval. how did u do it if it didnt give the population proportion? There was another question about finding the mean temperature of horses given 2 probabilities (one was like p(x>100.5=15.87) and p(x<???)=.30??) How did u do that without the st dev? i guessed on both lol
