If your research gives you a statistic that 70% of Americans are health conscious, then compare that to the amount of money spent each year on fast
food in America, you will probably find a conflict in those numbers. This would be evidence that your study lacked_validity.

Answers

If a research study indicates that 70% of Americans are health conscious, but when compared to the amount of money spent on fast food in America, a conflict arises, it would suggest a lack of validity in the study.

Validity refers to the extent to which a study accurately measures or reflects the concept it claims to be studying.

In this case, the conflict arises because the high percentage of health-conscious individuals does not align with the substantial amount of money spent on fast food.

If the study had strong validity, we would expect to see a correlation between health consciousness and a corresponding decrease in fast food consumption or expenditure. However, the evidence suggests otherwise.

The lack of validity may be due to various reasons such as flawed data collection methods, biased sampling techniques, or inaccurate survey questions.

It is essential to critically evaluate the study's methodology and data to identify any potential sources of error or bias that could have contributed to the conflict between the reported health consciousness percentage and the expenditure on fast food.

Sodium 24 has a half-life of approximately 15 hours. Consider a sample of 100 milligrams.

Write an equation to determine the number of milligrams remaining after t days. Show all work.
How many milligrams are remaining after 45 hours? Show all work.
How long will it be until there are 5 milligrams remaining? Show all work.

Answers

The decay equation is: N(t) = [tex]N0 * (1/2)^(t/T),[/tex] where N0 is the initial amount, T is the half-life, and t is time.

How to find the milligrams are remaining after 45 hours

For 45 hours, t = 45/24 = 1.875 days.

Plug values into the equation:

N(1.875) = [tex]100 * (1/2)^(1.875/0.625)[/tex]

= [tex]100 * (1/2)^3[/tex] = 12.5 milligrams.

To find when there are 5 milligrams left,

5 = [tex]100 * (1/2)^(t/0.625).[/tex]

Solving for t: t = 0.625 * log2(100/5)

= 0.625 * 4.322 = 2.70 days.

It enables people to connect and use each others special skills, resources, and goods. Globalization is not a new idea. It has been around for as long as people traveled to distant lands and nations.

Globalization is good. People can instantly share ideas and information through the Internet. Economic advantages benefit both rich and poor countries of the world. Competition between countries encourages wise use of resources. There are political advantages, too. People now recognize that they rely on each other. They depend on cooperation from each other. Some people feel differently about globalization. They think it hurts poor people. They also feel that some countries impose their culture on others through social media and the film industry.
