Question
1. How do confidence intervals relate to the material from last week, where you learned how to convert z-scores to probabilities using Appendix A1 of Field? Suppose a friend asked you to estimate what the temperature would be on October 15, 2018, and asked you to provide a range of possible temperatures (e.g. 55 to 65 degrees Fahrenheit). 2. what would your range be if you wanted to have a 99% chance of being correct? 3. Imagine your friend's guess was that it would be somewhere between 60 and 80 degrees. Just based on your knowledge of past weather, what is your estimate of the probability that your friend's guess will end up being correct? 4. Another friend joins your conversation and says that he predicts it will be between 75 and 77 degrees. Just based on your knowledge of past weather, what is your estimate of the probability that your friends guess will end up being correct? 5. Based on your answers to questions 2-4, what is the relationship between confidence (chance of being correct) and precision (how big or small is the range of someone's guess)?Explanation / Answer
