Aresearcher wonders if there an association between the incidence of colds and the amount of vitamin c taken. he recruits 88 volunteers and randomly assigns 31 of them to take 500 mg of vitamin c, 15 of them to take 1000 mg of vitamin c and the rest to take no vitamin c. at the end of the study, it was determined that 28 of the volunteers did not have any colds where 18 of them were in the 500 mg group and 5 of them were in the 1000 mg group. test the appropriate hypothesis at α = .05 .

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

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)
