Answer:

A paired T- Test

Step-by-step explanation:

In a paired sample t-test, every entity is measured two times(twice), resulting in pairs of observations. It is used to determine whether the mean difference between two sets of observations is zero or not.

An example would be to measure performance of patients before and after the medicine and analyze difference using sample paired t test.

<u><em /></u>

<em>Here, in the given statement, each student is provided with 15 multiple choice questions and 15 open ended questions on same material. It can also be inferred as each student given two sets of same material and their performance was being observed. Hence, it is a paired t-test.</em>

ANSWER


C. 58°


EXPLANATION


The sum of the interior angles of a triangle is 180°.


We sum all the three angles to obtain,


8x+(14x+2)+(10x+50)=180.


We group like terms to get,



8x+14x+10x+2+50=180.


Simplify,



32x+52=180.


Combine like terms to get,


32x=180-52.


Simplify,


32x=128.



Divide both sides by 32 to get,



x=4.


We substitute the value of x into the expression for



m\:.


This implies that,


m\:.



m\:.



m\:.



The correct answer is C
