Question

give an example of real-world research questions that would require you to do each of the following...

(a) determine whether a sample is different from a population

(b) whether two samples (i.e., groups) are different from each other.

Answer 1

Given to find the example of a real world research questions that would require you to do the following

a) To determine whether a sample is different from the operation -

The Population implies an aggreagate of an item under investigation is called populace test: Any piece of populace. EX. To check nature of grain of a sack grain of a sack: population a handful grain from a sack is a sufficient to check a quality of grain therefore handful grain is sample

b) To check whether 2 samples bare different or not-

There are two kinds of testing Inspecting with substitution Consider a populace of potato sacks, every one of which has either 12, 13, 14, 15, 16, 17, or 18 potatoes, and every one of the qualities are similarly likely. Assume that, in this populace, there is actually one sack with each number. So the entire populace has seven sacks. On the off chance that I test two with substitution, at that point I first pick one (state 14). I had a 1/7 likelihood of picking that one. At that point I supplant it. At that actually 49 distinct potential outcomes here (expecting we recognize the first and second.) They are: (12,12), (12,13), (12, 14), (12,15), (12,16), (12,17), (12,18), (13,12), (13,13), 13,14), and so forth. Examining without substitution: Consider a similar populace of potato sacks, every one of which has either 12, 13, 14, 15, 16, 17, or 18 potatoes, and every one of the qualities are similarly likely. Assume that, in this populace, there is actually one sack with each number. So the entire populace has seven sacks. In the event that I test two without substitution, at that point I first pick one (state 14). I had a 1/7 likelihood of picking that one. At that point I pick another. Now, there are just six potential outcomes: 12, 13, 15, 16, 17, and 18. So there are just 42 different possibilities outcomes here .They are: (12,13), (12,14), (12,15), (12,16), (12,17), 12,18), (13,12), (13,14), (13,15) etc
