First find all the closest pairs of points among this set of points.

(4,7) (1,3) (8, 10) (8,4) (12,8) (12,1)
(16,10) (16,3) (20,7) (20, 1) (27,8)

Then choose the point P below that has the following property:
If point P is added to the given set of points, then point P would be in a closest pair of points, and all the currently existing closest pairs would also still remain closest pairs.

a. (0,5)
b. (16,-1)
c. (14,4)
d. (22,11)

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels.ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
