Question 1. List twelve random numbers by yourself. Using that data, determine median, mean, mean absolute deviation, standard deviation of the population, and variance. Write all step-by-step solutions. If you don't write all step by step solutions, you will not get credit. (20 Points) Question 2. A group of engineering students who study together decide that they must use their time more efficiently. They decide that an equation that predicts their exam grade on the basis of number of hours studied will help them allocate their time more efficiently. Prepare a table on the basis of their performance on the last exam that shows number of hours studied and grades they got (fill in table below). What linear equation correlates their performance? (15 Points) Students Hours Studied (x1) Grade (vi) Zy - m(Ex m = (NEXy - Ex Ey) b = 1 N(Ex2) - (Ex)2 N 10 11 12 Question 3. Estimate the cost of concrete that is in the roadbed of GA-400 freeway running between Exit 5 and Exit 12. In order to solve this problem, you should make multiple reasonable assumptions.
