Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.
---------------------------
- 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as
. - Thus, a total of 511000 cigarettes, as
. - Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as
- One year has 525600 minutes, thus the person loses 14 years of life, as
- Looking at the decimal part, the person loses 212 days of life, as
- Again looking at the decimal part, 22 hours, as
- Thus, the person loses 14 years, 212 days and 22 hours of life.

Answer:
Null hypothesis = 
Alternate hypothesis =
Step-by-step explanation:
Given : In a recent semester, the proportion who earned a bachelor's degree within six years was 0.395.
The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate.
To Find : Determine the null and alternative hypotheses.
Solution:
In a recent semester, the proportion who earned a bachelor's degree within six years was<u> 0.395. </u>
Claim : the proportion of students who enroll in her institution <u>have a higher completion rate.</u>
So,null hypothesis =
Alternate hypothesis =
First of all, I find it easiest to write n equation.
3 / 15 x 8 =
Now that we have an equation, we can figure out a solution.
3 / 15 = 5
5 x 8 = 40
So 8 DVD's would cost $40.00.
