As practiced by many in buying skirts or pants, they use the neckline to check if the waistline of the skirts or pants fits them. We would like to study this claim by using a random sample of neckline and waistline of 15 people. The data collected are summarized in the table. Subject 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Neckline (in cm) 33 30 40 35 42 39 35 37 39 39 44 44 42 32 41 Waistline (in cm) 83 68 71 78 96 92 67 76 84 83 96 98 101 73 77 Construct a scatter plot for the waistline and neckline using the data presented in the table. (There is no need to upload this scatter plot.) What does the scatter plot tell you about the possible relationship between neckline and waistline? (choose the letter of the correct answer) a. Neckline and waistline seem to have positive linear relationship.b. Neckline and waistline seem to have negative linear relationship.c.
