An individual’s income varies with his or her age. The following table shows the median income I of males of different age groups within the United States for 2012. For each age group, let the class midpoint represent theindependent variable, x. For the class “65 years and older,” we will assume that the class midpoint is 69.5. (a) Use a graphing utility to draw a scatter diagram of thedata. Comment on the type of relation that may existbetween the two variables.(b) Use a graphing utility to find the quadratic function ofbest fit that models the relation between age and medianincome.(c) Use the function found in part (b) to determine the age atwhich an individual can expect to earn the most income.(d) Use the function found in part (b) to predict the peakincome earned.(e) With a graphing utility, graph the quadratic function ofbest fit on the scatter diagram.
Suppose at your university you are asked to find the relationship between weekly hours spent studying (study) and weekly hours spent working (work). Does it make sense to characterize the problem as inferring whether study “causes” work or work “causes” study? Explain.

The data show the test results from students in two classrooms, one integrated and one not. There are two sets of test scores, a pre-test and a post-test for both groups. First, calculate a measure of change in the test scores for students in both groups. Then, use the resulting measure of change to compare both groups on the measure of change from the pre-test to the post-test. When finished, write a short summary of what you found, including: Group 1 mean Group 2 mean Ho and H1 t-observed t-critical
Measuring the height of a California redwood tree is very difficult because these trees grow to heights of over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees. Interpret the meaning of the coefficient of determination in this problem. Perform a residual analysis on the results and determine the adequacy of the model. Determine whether there is a significant relationship between the height of redwood trees and the breast height diameter at the 0.05 level of significance.
