A pharmaceutical company is conducting a study of the efficacy of a drug and it is believed to increase the life expectancy of mice. The drug was compared to a control group and a re-randomizing simulation was used to create the distribution graph below. The sample size was 100. They found that on average, the mice lived 1 month longer than the control group. Does this indicate that the drug is effective and why?

it is $66

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: it's a
