SOLVE: Give a 90% condence interval for the mean load required to pull apart the wood. Suppose that the strength of pieces of wood like these follows a Normal distribution with standard deviation 3000 pounds. Give your answers to two decimal places. An SRS of 350 high school seniors gained an average of Suppose we had an SRS of just 100 high school seniors. i = 45 points in their second attempt at the SAT What would be the margin of error for 99% condence? Mathematics exam. Assume that the change in score has a Give your answer to three decimal places. Normal distribution with standard deviation 6 = 26
