Answer to Problem 7.2P

1.1 to 1.4

Explanation of Solution

Given:

ERR is 0.1-0.4 per Gy.

Formula used:

  ProbabilityofCausation=ERR1+ERRRR=1+ERR

Calculation:

  RR=1+ERRRR=1+0.1RR=1.1RR=1+0.4RR=1.4

Conclusion:

The RR per gray is 1.1-1.4

the V•O2max of people tends to declineafter age 30 by about 9% per decade for sedentary individuals,but it declines less than 5% per decade for people who stay active.The average V•O2max in healthy 30-year-olds is about 3.1 L/min.Using the information given here, what would the average V•O2maxbe in 60-year-olds who have been sedentary throughout theirlives and in 60-year-olds who have stayed active (keep in mindthat the decline is exponential)?
