Natural pairings defines coupling of data sets or sample is possible to take place in a particular condition naturally.These samples depend on each other for matching.

According to the question ,cholesterol level of 90 men is being assessed prior and after treatment takes place.Thus,same 90 men are going through drug testing in natural pair form and showing sample dependency before and afterwards of treatment.Thus, further analysis is based upon natural paired data.

Other options are incorrect because sample in the question are not independent due to the link between them and they do persist natural pairing with each other.Thus, the correct option is option(D).

You are traveling by car from Covington, GA to Savannah, GA – a distance of about 240 miles. You are moving at 60 miles per hour

Degger [83]

Answer:

Speed = Distance/Time. so if you rearrange this it means that you get Time = Distance/Speed. Therefore 240/60 = 4 then you just think of doing miles(distance)/Miles per hour(speed) which leaves you with 4 hours which=C

Step-by-step explanation:

Sometimes to make it easier i use a triangle from this equation, you cover up what one you want and then you do what it says. If you cover up distance then you are left with speed x time. Likewise if you cover up speed. Speed = Distance / Time.
