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, 13 of 18 repairs were successful while for shorter tears, 23 of 30 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). (a) There 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).

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
