Medical research has shown that repeated wrist extension beyond 20 degrees increases the risk of wrist and hand injuries. Each of 24 students at a university used a proposed new computer mouse design. While using the mouse, each student's wrist extension was recorded. Data consistent with summary values in a paper are given. 27 24 25 26 27 28 28 25 25 25 28 21 28 25 24 27 26 32 28 24 27 27 24 28 Use these data to test the hypothesis that the mean wrist extension for people using this new mouse design is greater than 20 degrees. Find the test statistic and P-value. (Use a = 0.05. Use technology to calculate the P-value. Round your test statistic to two decimal places and your P-value to four decimal places.) t 14.90 X P-value = 0
