Answer:

B. Independent-samples t test

Step-by-step explanation:

The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.

Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.

Thus, the best test to use in this case will be the Independent-samples t test

What is the value of n
Crank

Answer:

The correct answer is option D. 69°

Step-by-step explanation:

Points to remember

1). The sum of angles in a linear pair is 180°

2). In a triangle sum of two angles are equal to the exterior angle of third angle

From the figure we can see a triangle in which two exterior angles area given.

<u>To find the value of n</u>

from figure we get,

n = (interior angle of 131°  + interior angle of 160°)

interior angle of 131° = 180 - 131 = 49°

interior angle of 160° = 180 - 160 = 20°

n =  49° + 20° =  69°

Therefore the  correct answer is option D. 69°
