Question

In the above study, the investigators determined that a low concentration of dnp increased the average life span from 719 days (control) to 770 days (dnp). if the u. s. population has an average life span of 79 years, then how many years would be added if the same percentage increase were observed? express your answer using two significant figures.

Answer 1

Average life span population

Explanation:

• A study done by the group of investigators in america determined that by decreasing the concentration of dnp will increase the average life from 719 days of a control population to 770 for dnp controlled population or by 1.07.
• So the average lifespan of every individual will increases roughly 5.6 years so as average lifespan will increase from 719 to 770 days.
• Hence, the right answer is " 5.6 years would be added the same percentage increase were observed."
