Answer:
Two sample t test
Explanation:
The test that could be used here is the two sample t test. The two sample t test compares two groups to ascertain if there is an average significant different between the two groups being compared, also making sure the result of difference is not random. For instance to test the above example, the two sample t test compares the group before they watch the commercial with the group after the commercial to know if there is a significant difference between the two groups.

Answer:
D. 12
Step-by-step explanation:
There are a number of ways to find the area of this rectangle. Perhaps the most straightforward is to find the lengths of the sides and multiply those. The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the two upper-left points, we find the length of that side to be ...
d = √((3 -0)^2 +(3 -0)^2) = √(9 +9) = √18 = 3√2
Similarly, the length of the lower-left side is ...
d = √((-2 -0)^2 +(-2 -0)^2) = √(4+4) = √8 = 2√2
Then the area of the rectangle is ...
A = LW
A = (3√2)(2√2) = 3·2·(√2)^2 = 3·2·2 = 12
The area of rectangle ABCD is 12.
_____
Other methods include subtracting the area of the corner triangles from the area of the bounding square:
5^2 -2(1/2)(3·3) -2(1/2)(2·2) = 25 -9 -4 = 12
Figure is shown for graph of y=1.5sin4x
The equation of sin function is given as
Where A is Amplitude of function and T is Time period
Given sin function is
A) Compare the amplitude of y=1.5sin(4x) to the amplitude of y=sin x
Ans
In y=sin x, Amplitude is 1 unit
In y=1.5sin4x, Amplitude is 1.5 unit
B) compare the period of y=1.5sin(4x) to the period of y=sinx
In y=sin x, Time period is
T =
In y=1.5sin4x, Time period is
C) Plot the graph for 2 period
Shown in figure.
