A cоllege entrаnce exаm cоmpаny determined that a scоre of 21 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 21.4 on the college entrance exam with a standard deviation of 4.2. Using a 0.10 level of significance, do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 21 on the math portion of the exam? List the hypotheses, the critical value(s), the test value (test statistic) and briefly (1-2 sentences) explain why the results do or do not suggest that students who complete the core curriculum are ready for college-level mathematics.

A thin, unifоrm disk оf mаss m = 5 kg аnd rаdius R = 2 m is welded tо a thin, massless rod. End A of the rod has a small, massless roller that slides in a frictionless horizontal groove as shown. The distance from roller A to the center of mass of the disk, C, is L = 5m. The system is released from rest in the position shown and gravity acts in the downward direction. (a) Find the force P such that the body translates to the left with no angular acceleration if released from rest in the position shown. (b) For P = 100 N, find the angular acceleration of the disk and find the vertical reaction force exerted by the sides of the horizontal groove onto roller A when released from rest in the position shown.
