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. 27 24 26 27 25 25 24 24 24 25 28 24 28 27 26 31 25 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.) 24.206 (b) What assumptions are required in order for it to be appropriate to generalize your estimate to the population of students at this university? O Yes, the assumption would have to be made that the 24 students in the study formed a random sample of people in the country. O Yes, the assumption would have to be made that the 24 students in the study formed a random sample of students at this university. O Yes, the assumption that the 24 students in the study formed a random sample of students at all universities. O No, we cannot generalize the estimate to any population as we have less than 30 students. O No, we can generalize the estimate to the population of students at this university. To the population of all university students? O No, we can generalize the estimate to the population of all university students. O Yes, the assumption would have to be made that the 24 students in the study formed a random sample of people in the country. O No, we cannot generalize the estimate to any population as we have less than 30 students.
