Medical research has shown that repeated wrist extensions beyond 20 degrees increase the risk of wrist and hand injuries. Each of 24 students at a university used a proposed new computer mouse design, and while using the mouse, each student's wrist extension was recorded. Data consistent with summary values given in a paper are given here. 26 28 23 25 27 25 25 24 24 24 25 28 22 25 24 28 27 26 31 25 LUSE SALT 28 27 27 25 (a) Use these data to estimate the mean wrist extension for people using this new mouse design using a 90% confidence interval. (Round your answers to three decimal places.) (b) What assumptions are required in order for it to be appropriate to generalize your estimate to the population of students at this university?
