Randomization is important to ensure that both groups are roughly equivalent regarding students’ preparedness, anxiety levels, and study skills.
<h3>What is randomization in an experiment?</h3>
Randomization is when subjects in an experiment are placed in either the control group or the treatment group without any structure. They are placed in either groups randomly. The purpose of randomization is to ensure that subjects in either group are homogenous.

Answer:
456 students
Step-by-step explanation:
38% = 0.38
1200 x 0.38 = 456
Answer:
a. The amplitude should be 2.
The period should be 2\pi.
b. maximum value occurs in (0,1) at x = 0
minimum value occurs in (pi,-1) at x = pi
Step-by-step explanation:
Answer:
x = 2.285 hours
y = 2.1425 feet
Step-by-step explanation:
Let us say that y represents the depth of the pool in feets and x represents the time in hours
The two set of equations are
y = 1/2x + 1
y= -1.25x + 5
Solving the above two equations we get
Subtracting eq (1) from eq (2), we get -
y-y = -1.25 x -0.5 x + 4
0 -1.75 x + 4
x = 4/1.75
x = 2.285 hours
y = 0.5 * 2.285 + 1
y = 2.1425 feet
