Question

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.)

28	26	25	24	28	27	27	25	25	25	27	26
22	27	25	26	28	24	31	27	26	28	28	27

State the appropriate null and alternative hypotheses.

H₀: ? = 20

H_a: ? < 20

H₀: ? < 20

H_a: ? > 20

H₀: ? = 20

H_a: ? ≠ 20

H₀: ? > 20

H_a: ? < 20

H₀: ? = 20

H_a: ? > 20

Find the test statistic and P-value. (Round your test statistic to one decimal place and your P-value to three decimal places.)

P-value=
