An article in Knee Surgery, Sports Traumatology, Arthroscopy (2005, Vol. 13, pp. 273-279), considered arthroscopic meniscal repair with an absorbable screw. Results showed that for tears greater than 25 millimeters, 15 of 17 (88%) repairs were successful while for shorter tears, 23 of 31 (74%) repairs were successful.
(a) Is there evidence that the success rate is greater for longer tears? Use alpha=0.05 . What is the P -value?
(b) Calculate a one-sided 95% confidence bound on the difference in proportions that can be used to answer the question in part (a).
Solution format:
(a) There (is or is not) evidence that the success rate is greater for longer tears. The P -value is Round your answer to four decimal places (e. g. 98.7654).
(b) The one-sided 95% confidence bound is ? <=p1-p2 . Round your answer to three decimal places (e. g. 98.765).

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
