- Find the measure of the least positive angle that is coterminal with the given angle. 20°In a section of an English 201 class, the professor decides to be "generous" with the students and will grade the exam in a unique way. Grades will be assigned according to the follwing rule: the top receives A's, the next 20% receive B's, the middle 40% receive C's, the next 20% receive D's, and the bottom 10% receive F's. Some may refer to this as "curving" The 40 grades were as follows: 30, 53, 88, 69, 77, 57, 58, 43, 63, 51, 69, 88, 86, 84, 50, 83, 91, 76, 57, 90, 45, 79, 41, 80, 62, 66, 71, 58, 92, 85, 57, 74, 63, 60, 99, 85, 70, 93, 67, 53 Do you think ths method of grading is fair to all students? Explain your answer 2. Under what circumstances would some students NOT like this method of grading? 3. Find the lowest score on the final exam that would qualify a student for an A, a B, a C, and a D 4.

Sholl et al. published the results of examining the sense of direction of 30 male and 30 female students. Afterbeing taken to an unfamiliar wooded park, the students were given some spatial orientation tests, including pointingto south, which tested their absolute frame of reference. The students pointed by moving a pointer attached to a 360◦protractor. Following are the absolute pointing errors, in degrees, of the participants.
