Question

Polyunsaturated fatty acids in the diet favorably affect several risk factors for cardiovascular disease. The principal dietary polyunsaturated fat is linoleic acid. Suppose we randomly selected twelve adults for our study. We took their blood pressure measurements (systolic blood pressure) at the start and recorded them for each adult. Then we placed required these adults to consume 23g/day of safflower oil which is high in linoleic acid for four weeks. At the end of the four weeks, we took another systolic blood pressure(SBP) measurement. The paired data is provided below:

Subject	1	2	3	4	5	6	7	8	9	10	11	12
Baseline SBP	119.67	100.00	123.56	109.89	96.22	133.33	115.78	126.39	122.78	117.44	111.33	92.39
1-month SBP	117.33	98.78	123.83	107.67	95.67	128.89	113.22	121.56	126.33	110.39	107.00	93.06

Use the appropriate nonparametric test at alpha level of 0.05, to test whether the diet heavy in linoleic acid increases systolic blood pressure (SBP).
