An article in Knee Surgery, Sports Traumatology, Arthroscopy considered arthroscopic meniscal repair with an absorbable screw. Results showed that that for tears greater than 25 mm, 14 of the 18 repairs were successful and for shorter tears, 21 of 30 repairs were successful. Is there evidence that the surgery is more successful for longer tears? Include the null and alternative hypothesis, pvalue, and write your conclusion in the context of the problem (including Reject Ho or Do not reject Ho). Use μ=0.01.
