You may read in the newspaper that a study of a new drug for cancer "increased survival by an average of eight weeks." it turns out that this is a median, and it is used for complicated statistical reasons. but in a perfect world, would you prefer to know the increase in mean or median survival?

rounding to the nearest thousandth would be 452,000

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

answer is  

a.

p = 78
