Learn Relative Risk with Plainmath's In-Depth Explanations and Real-World Examples

Use the information at the beginning of the lesson. The Palermo scale value of any object can be found using the equation
$PS={\log }_{10}R$
where R is the relative risk posed by the object. Write an equation in exponential form for the inverse of the function.

If the baseline risk of a certain disease for nonsmokers is 1% and the relative risk of the disease is 5 for smokers compared to nonsmokers, what is the risk of the disease for smokers?

For the study with the headline "coffee Gives Jolt to Lifespan, over 400,000 adults aged 50 to 71 were studied for 13 years as part of the NIH-AARP Diet and Health Study. They completed a questionnaire asking about 124 dietary items in addition to demographic and lifestyle variables. Results were reported separately for men and women and for differing amounts of coffee consumption. The hazard ratio for death (somewhat similar to a relative risk) for men who drank 2 or 3 cups of coffee a day was estimated to be 0.88, with a 95% confidence interval from 0.84 to 0.93, indicating that they were less likely to die during the study than men who drank no coffee. Explain how each of the following numbered items from the Ten Guiding Principles on would apply to this study. Guiding principle 2. Guiding principle 6. Guiding principle 8. Guiding principle 9.

How does the risk of having an identical twin with schizophrenia compare to the risk of having a fraternal twin with schizophrenia?
A.The risk is the same.
B. The risk is twice as great
C. The risk is twice as great.
D The risk is four times as great

For a relative risk of 1.53, what is the percent increase in risk? For a percent increase in risk of 140%, what is the relative risk?

The concentration of alcoholin a person's bloodstream is measurable.
Suppose that the relative risk R of having an accident while driving a car can be modeled by an equation of the form $R=e^{kx}$ where x is the percent of concentration of alcohol in the bloodstream and k Is a constant Using this value of k, what is the relative risk if the concentration is 0.17 percent?

Which of the following statement is true?
(a) Risk behaviors are illegal for everyone.
(b) Risk behaviors can harm your health.
(c) Most teens engage in risk behaviors.
(d) There is no way to avoid risk behaviors.

For a relative risk of 2.1, what is the percent increase in risk? For a percent increase in risk of 40%, what is the relative risk?

According to a study on partner abuse reported by the Sacramento Bee, 25% of women with male partners had been assaulted by their current or a former partner, whereas 11 % of women with female partners had been assaulted. What is the relative risk of assault for women with male partners compared to women with female partners? Answer ina sentence that would be understood by someone with no training in statistics.

The ultimate risk in driving is having a crash. Name two risk factors for each of the three risk factor groups that could increase risk?

When it comes to investing, what is the typical relationship between risk and return?
A-There is no relationship between risk and return
B-The greater the potential risk, the smaller the potential return
C-The greater the risk, the greater the potential return
D-It depends on the investment mix in your portfolio

The ability of insurance to spread risk is limited by
a. risk aversion and moral hazard.
b. risk aversion and adverse selection.
c. moral hazard and adverse selection.
d. risk aversion only.

Distinguish among beta (or market) risk, within-firm (or corporate) risk, and stand-alone risk for a project being considered for inclusion in the capital budget

In theory, market risk should be the only "relevant" risk. However, companies focus as much on standalone risk as on market risk. What are the reasons for the focus on standalone risk?

The benefit of diversification when constructing a portfolio is that it can eliminate
a. speculative bubbles.
b. risk aversion.
c. firm-specific risk.
d. market risk.

For each of the following measures, give the value that implies no difference between the two groups being compared. Relative risk. Odds ratio. Percent increase in risk.

The concentration of alcohol in a person's bloodstream is measurable. Suppose that the relative risk R of having an accident while driving a car can be modeled by an equation of the form $R=e^{kx}$ where x is the percent of concentration of alcohol in the bloodstream andk is a constant. Suppose that a concentration of alcohol in the bloodstream of 0.03 percent results in a relative risk of an accident of 1.4. Find the constant k in the equation.

The concentration of alcohl in a person's bloodstream is measurable. Suppose that the relative risk R of having an accident while driving a car can be modeled by an equation of the form $R=e^{kx}$ where x is the percent of concentration of alcohol in the bloodstream and k is a constant. If the law asserts that anyone with a relative risk of having an accident of 5 or more should not have driving privileges, at what concentration of alcohol in the bloodstream shoulda driver be arrested and charged with a DUI?
