Medical research has shown that repeated wrist extension beyond 23 degrees increases the risk of wrist and hand injuries. Each of 61 subjects used a computer mouse, during which each subject’s wrist extension was recorded. The mean wrist extension for these 61 subjects was 24.8 degrees, with a standard deviation of 4 degrees. Do the data suggest that the true mean wrist extension for computer mouse users exceeds 23 degrees?
