Homework: Section 12.3 Martha Janelle Casso You can attempt each problem twice, then the answer will be shown on your third attempt. You can attempt each problem as many times needed as long as it is before the due date. When reattempting a problem, you will receive a similar problem, not the exact previous problem. You can keep on working on versions of a question until you get a perfect score on the exercises. The staff at the Math Success Center may help you on this assignment. Question 1 0/10 pts 3 9

Question 2 0/10 pts 3 9 a. -0.34 b. -0.95 c. 0.49 d. 0.93 Match each scatterplot shown below with one of the four specified correlation coefficients. - - - -

Question 3 0/10 pts 3 9 Question 4 0/10 pts 3 9 Question 5 0/10 pts 3 9 Predict the value of the second quiz score if a student had a score of on the first test. A researcher wishes to examine the relationship between years of schooling completed and the number of pregnancies in young women. Her research discovers a linear relationship, and the least squares line is: where is the number of years of schooling completed and is the number of pregnancies. The slope of the regression line can best be interpreted in the following way: When amount of schooling increases by one year, the number of pregnancies increases by 3. When amount of schooling increases by one year, the number of pregnancies increases by 5. When amount of schooling increases by one year, the number of pregnancies decreases by 5. When amount of schooling increases by one year, the number of pregnancies decreases by 3. Question Help: Video Using your favorite statistics software package, you generate a scatter plot which displays a linear form. You find a regression equation and the standard deviation for both variables. The standard deviation for x is 0.74, and the standard deviation for y is 3.36. The regression equation is reported as What fraction of the variation in y can be explained by the variation in the values of x ? (Enter your answer as a decimal between 0 and 1.)
