Question 2 < SAT scores are distributed with a mean of 1,500 and a standard deviation of 300. You are interested in estimating the average SAT score of first year students at your college. If you would like to limit the margin of error of your 95% confidence interval to 25 points, how many students should you sample? Make sure to give a whole number answer.
m Question 3 T < > A student was asked to find a 90% confidence interval for widget width using data from a random sample of size n 16. Which of the following is a correct interpretation of the interval 11.4<p < 25.5? Check all that are correct. The mean width of all widgets is between 11.4 and 25.5, 90% of the time. We know this is true because the mean of our sample is between 11.4 and 25.5. There is a 90% chance that the mean of a sample of 16 widgets will be between 11.4 and 25.5. There is a 90% chance that the mean of the population is between 11.4 and 25.5. With 90% confidence, the mean width of all widgets is between 11.4 and 25.5. With 90% confidence, the mean width of a randomly selected widget will be between 11.4 and 25.5. 0/5 pts 2 Detai
