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 and while using the mouse each student s wrist extension was recorded Data consistent with summary values given in a paper are shown Use these data to test the hypothesis that the mean wrist extension for people using this new mouse design is greater than 20 degrees Use 0 05 24 H 22 26 25 28 24 27 25 26 24 LUSE SALT 27 27 25 25 25 27 28 31 27 26 24 26 State the appropriate null and alternative hypotheses in degrees Enter for as needed Ho Find the test statistic Round your answer to two decimal places 24 27 Content Use technology to find the P value Round your answer to four decimal places P value W Exam 3 MATH1123 section 08 Fall 2023 WebAssign State your conclusion We fail to reject Ho We have convincing evidence that the mean wrist extension for all people using the new mouse design is greater than 20 degrees We fail to reject Ho We do not have convincing evidence that the mean wrist extension for all people using the new mouse design is greater than 20 degrees We reject Ho We have convincing evidence that the mean wrist extension for all people using the new mouse design is greater than 20 degrees We reject Ho We do not have convincing evidence that the mean wrist extension for all people using the new mouse design is greater than 20 degrees Are any assumptions required in order for it to be appropriate to generalize the results of your test to the population of students from this university We need to assume that the 24 students used in the study are representative of all students who own PCs We need to assume that the 24 students used in the study are representative of all students who use a wireless mouse Wo good to assume that the 24 students used in the study are representative of all students at the university all pudents with a history of wrist or hand injuries
