a) Find the average of: 20, 25, 30, 35, 40, 50, 60, 70, 90 b) Find the median of : 20, 25, 30, 35, 40, 50, 60, 70, 90 c) Find the average of: 20, 25, 30, 35, 40, 50, 60, 70, 900 d) Find the median of : 20, 25, 30, 35, 40, 50, 60, 70, 900 e) What do the above examples show about one difference between the mean and the median of a set of numbers? f) What is the standard deviation of the numbers in 1a? What does the standard deviation measure? 2. given the data below: Age (months) Avg Weight (lbs) 0 8 18 28 2 4 a) What is the average weight at birth? b) Write an equation that models age and avg weight c) How much avg weight does the baby gain every month? d)What are the range and domain of your equation? e) What might you predict a 10 month old's avg weight to be? f) Do you have much confidence in your answer? Why? Or Why not? 3. Draw the graph of the equation in question 2. a) Find the average of: 20, 25, 30, 35, 40, 50, 60, 70, 90 b) Find the median of : 20, 25, 30, 35, 40, 50, 60, 70, 90 c) Find the average of: 20, 25, 30, 35, 40, 50, 60, 70, 900 d) Find the median of : 20, 25, 30, 35, 40, 50, 60, 70, 900 e) What do the above examples show about one difference between the mean and the median of a set of numbers? f) What is the standard deviation of the numbers in 1a?
