Transcribed Image Text:Some sports that involve a significant amount of running, jumping, or hopping put participants at risk for Achilles tendon injuries. A study looked at the diameter (in mm) of the injured tendons for patients who participated in these types of sports activities.
Suppose that the Achilles tendon diameters in the general population have a mean of 5.97 millimeters (mm). When the diameters of the injured tendon were measured for a random sample of 34 patients, the average diameter was 9.90 mm with a standard
deviation of 1.99 mm. Is there sufficient evidence to indicate that the average diameter of the tendon for patients with Achilles tendon injuries is greater than 5.97 mm? Test at the 5% level of significance.
State the null and alternative hypotheses.
O Ho: μ = 5.97 versus H₂: μ # 5.97
O Ho: μ< 5.97 versus H₂: μ> 5.97
O Ho: μ = 5.97 versus H₂: μ> 5.97
O Ho: μ = 5.97 versus H₂: μ< 5.97
O Ho: μ # 5.97 versus H₂: μ = 5.97
Find the test statistic and rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.)

State your conclusion.
O Ho is rejected. There is insufficient evidence to indicate that the average diameter of the tendon for patients with AT is greater than 5.97 mm.
O Ho is not rejected. There is sufficient evidence to indicate that the average diameter of the tendon for patients with AT is greater than 5.97 mm.
O Ho is rejected. There is sufficient evidence to indicate that the average diameter of the tendon for patients with AT is greater than 5.97 mm.
O Ho is not rejected. There is insufficient evidence to indicate that the average diameter of the tendon for patients with AT is greater than 5.97 mm.
