Suppose that we were going to conduct a study to determine if there is an increased risk of getting lung cancer based on whether the person excerises regularly or not. In our excerising regularly group(1), we find than 2 out of 100 get lung cancer. In our non excersing group(2), we find that 5 out of 100 get lung cancer. What is the sample relative risk? (Give to one decimal place.)
And best answer will not go to anyone who tells me "do your own homework" (surprise surprise) If I knew how to do this, or how to find out, I wouldn't be wasting the time or the points.

so, you divide (5/100) by (2/100).
This simplifies to 5/2
which is 2.5.
This tells you that (assuming a well structured research study) you are 2.5 times as likely to get lung cancer if you don't exercise than if you do.

that may no longer even on the factor of being actual. Homeschooled youngsters outshine public and private college scholars in virtually each and every section, and are particularly properly socialized additionally. Very intense reaching youngsters. It was once actual that maximum homeschooled youngsters have been from fundamentalist Christian familes - this hasn't been the case for some years now. moms and dads from all walks of existence observed the horrid circumstances and academic standards in public faculties and started homeschooling their babies. As for government regulation, there are rules in each and every state that govern what share hours of what subject remember could learn - in many circumstances they are the comparable rules that the well-known public faculties could abide via - with the variation being that homeschooled youngsters pass above and previous those limits, via a protracted way. so which you're able to desire to reply to your question - no. the government does no longer want any further regulation than already exists. moms and dads are doing an excellent hobby homeschooling their youngsters, and their youngsters are turning out wonderful the two educationally and socially. P.S. Outsourcing to India, and so forth. has no longer something to do with the academic stages of absolutely everyone interior of u . s . a . of america of u . s . a . of america. that's all approximately economics for those firms that are doing the outsourcing. firms pass to distant places international locations and hire workers there (maximum of whom have in no way been previous grade college) for pennies on the dollar. that's the reason firms outsource.

the relative risk would be 3/100 or .03% as people who do not exercise get 3 more victims for every hundred. if they only want one decimal place, i guess your answer is .0%, but that hardly makes sense as an answer. is this for a statistics class? if it is, is it one of the concept questions?

I don't exactly undestand what you mean by "relative risk". With the exercise group, the average risk is 0.02, and for the other group, the average risk is 0.05. Are you looking for a ratio of risks or a difference of risks?

Wouldn't it be 7/ 200= .035 or 3.5%

2/100ths versus 5/100ths aka .02% and .05%
Now do your own homework!
