Answer: a) sample
b) quantitive.
Step-by-step explanation:
Given: A recently published research study looked at 3000 people over a period of 15 years and determined that those people who ate fast food two or more times per week had gained an average of 10 pounds more than the group who ate fast food less than twice a week.
Here, population = "people who ate fast food two or more times per week"
Since a census is the data of all members in a population whereas a sample is a subset of it.
Then, 3000 people constitute a sample as it is a subset of the population.
Since the researcher's point of interest it to measure average weight gain which is a quantitive measure.
So, the data is quantitative.
That's not an equation, and it doesn't ask any question. As it stands, there's nothing to "solve".
You may have been given an assignment to "simplify" it ... make it prettier and less complicated.
In order to do that, let's pretend for a moment that you're asked to add up a list that says:
4 chickens + 6 cows + 5 cows + 6 cows
I'm convinced that you would have no trouble at all adding up this list. You would
know right away that you can add up all the cows into one number, but you can't
add cows to chickens. You would simplify the list,and it would become <em>
4 chickens + 17 cows</em>.
And now that you understand that, you're all ready to simplify the expression
in your question. Just add up all the 'y's into a single number, but you can't
add 'y's to 'x's.
When you're done, you have 4x + 17y, and you're done. That's all you can do with it.
