Question

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 (cm)	41	35	35	38	33	34	34	30	41	40	36	35	30	32	33
Waistline(cm)	91	64	84	95	65	87	68	65	101	84	85	90	68	75	81

Construct a scatter plot for the waistline and neckline using the data presented in the table.

1. What does the scatter plot tell you about the sign of the slope of the regression equation? Positive or Negative?
2. Does the regression model estimated conform with the scatter plot?
