1. Given 3 students in a Statistics class. Compare their scores if in a series of 6 quizzes, their scores are: Student 1: 5 8 9 7 6 9 co to Student 2: 7 6 8 5 Student 3: 6 7 8 4 9 8 a. Which student tends to perform the best in the quizzes? b. Which student tends to perform the most inconsistently in the quizzes? 2. Given the set of scores: 3 5 9 12 16 19 20 19 22 Find the range, mean deviation, variance and standard deviation. Range = mean deviation = variance = standard deviation = 3. Below is a distribution of scores of students. x (Scores) 97 -98 95 -96 93 -94 N W N W O G NT 91 -92 89 - 90 87 - 88 85 - 86 a. Find the variance and standard deviation. Variance = Standard Deviation = 5. Office Products International produces white typing fluid (to cover typing mistakes) in two plants. One plant is in La Union (a mean of 15 ml bottle with SD = 10 ml) and another in Isabela (mean Of 7.5 ml and SD = 9ml. The quality control manager is concerned that the filling machine controls in La Union are not "tight" enough. Compare the relative dispersion of the two locations.1.
