Medical research has shown that repeated wrist extension beyond20 degrees increases the risk of wrist and hand injuries. Each of24 students at a university used a proposed new computer mousedesign. While using the mouse, each student's wrist extension wasrecorded. Data consistent with summary values given in a paper aregiven. Use these data to test the hypothesis that the mean wristextension for people using this new mouse design is greater than 20degrees. (Use
α = 0.05.
Use a statistical computer package to calculate theP-value. Round your test statistic to two decimal placesand your P-value to three decimal places.)

1. State your conclusion.
Reject H0. We have convincing evidence thatthe mean wrist extension for all people using the new mouse designis greater than 20 degrees.
2. Are any assumptions required in order for it to beappropriate to generalize the results of your test to thepopulation of students from this university?
We need to assume that the 24 students used in the study arerepresentative of all students at the university.

1. We need to assume that the 24 students used in the study arerepresentative of all students who use a wireless mouse.
2. We need to assume that the 24 students used in the study arerepresentative of all students at the university.
3.. We need to assume that the 24 students used in the study arerepresentative of all students who own PCs.
4. We need to assume that the 24 students used in the study arerepresentative of all university students.
5.We need to assume that the 24 students used in the study arerepresentative of all students in computer science classes
