Researchers want to investigate if students retain more information if it printed on blue paper rather than white paper. They recruit 100 elementary students, 100 middle school students, and 100 high school students to participate. The researchers then randomly assigned half of the elementary students, half of the middle school students, and half of the high school students to receive the information on blue paper. The remaining students receive the same information on white paper.

Write down the best describes this experimental design.
Answer:
Stratified design with color of paper as the blocks
Step-by-step explanation:
The experimental design that this question uses is the stratified design with color of paper as the blocks
A stratified design is one where the population has been divided into strata that are homogeneous. A good number of participants would then be picked for each of the stratum. The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here.
The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students. The students in each levels are halved and each half is randomly assigned information on either a white paper or a blue paper.

The experimental design that this question uses is the stratified design with color of paper as the blocks
Stratified sampling refers to a type of sampling method . With stratified sampling, the researcher divides the population into separate groups, called strata. Then, a probability sample (often a simple random sample ) is drawn from each group. Stratified sampling has several advantages over simple random sampling.The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here. The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students.

The following are the number of sales which a sample of 9 car salespeople of an insurance company in Florida and a sample of 8 salespeople in Washington made over a certain year. Florida: 39, 44, 42, 50, 55, 48, 51, 38, 54 Washington: 42, 43, 56, 50, 49, 52, 53, 56 Assuming that the populations sampled can be approximated closely with normal distributions having the same variance, is there a difference in the number of sales between the Florida salespeople and the Washington salespeople?
Find s^2p (round off to the nearest integer)
Answer:
There is no difference in the number of sales between The Florida salespeople and Washington salespeople
Sp^2 = 39
Step-by-step explanation:
Given data :
Florida: 39, 44, 42, 50, 55, 48, 51, 38, 54
Washington: 42, 43, 56, 50, 49, 52, 53, 56
number of sales persons in Florida = 9
number of sales persons in Washington = 8
variance = constant
a)Determine if there is difference between the Florida salespeople and Washington salespeople
we will carry out a two tailed test based on the given data
H0 : u1 = u2
H1 : u1 ≠ u2
x ( mean ) = 46.77, y ( mean ) = 50.13 ,
s1^2 = 39.69, s2^2 = 28.41, n1 = 9 , n2 = 8
therefore :
Sp^2 = [tex]\frac{n1s1^2 + n2s2^2}{n1 + n2-2}[/tex] = 38.96 ≈ 39
performing test statistic
t = [tex]\frac{x- y }{sp\sqrt{\frac{1}{n1} +\frac{1}{n2} } }[/tex] = [tex]\frac{-3.36}{3.0330}[/tex] = -1.1078
critical value is at t = 0.05 and for a two tailed test it is at 2.13 therefore e accept H0 at 5% . This shows that there is no difference in sales
Help plz!!! Are these equations equivalent?
x = 4 - 3x
2x = 4
Answer:
no
x = 4 - 3x x = 1
2x = 4 x =2
hope this helped :D
Answer:
No. They are not equivalent. The first one would end up being x=1, while the second one would be x=2.

Scatter plotsGiven the ordered pairs that Samantha needs to plot given as shown;
(19,9) , (8,6) , (10,14) and (4,15)From the given ordered pair, we can see that the outlier is (8, 6) because it lies an abnormal distance from other coordinate points.
We can see that as the x-values is increasing, the y-values is decreasing. Hence the ordered pairs that she still needs to plot are the remaining coordinate order than the outlier.

Find the inequality represented by the graph
Answer:
y ≤ -3/2 x -2
Step-by-step explanation:
slope = - 3/2
y intercept = -2
y ≤ -3/2 x -2
Pls solve it and show your work :((
Answer:
See below
Step-by-step explanation:
To graph the line we need two points, one point is the y-intercept, the second point to be calculated.
Q7
y = -3x + 6
The y-intercept is (0, 6)Let the domain be x = 5 for the second point, then:
y = -3*5 + 6 = -15 + 6 = -9The point is (5, -9)Connect these points to get the graph
Q8
y = 4/5x - 3
The y-intercept is (0, -3)Let the domain be x = 5 for the second point, then:
y = 4/5*5 - 3 = 4 - 3 = 1The point is (5, 1)Connect these two points to get the graph
Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating rectangle.
2x + y^2 = 48, x = y
Answer:
Attached please find response.
Step-by-step explanation:
We wish to find the area between the curves 2x+y2=8 and y=x.
Substituting y for x in the equation 2x+y2=8 yields
2y+y2y2+2y−8(y+4)(y−2)=8=0=0
so the line y=x intersects the parabola 2x+y2=8 at the points (−4,−4) and (2,2). Solving the equation 2x+y2=8 for x yields
x=4−12y2
From sketching the graphs of the parabola and the line, we see that the x-values on the parabola are at least those on the line when −4≤y≤2.
In this exercise we have to use the function informed to identify the value of the formed figure, then:
[tex]x=4-12y^2[/tex]
Given the following information in the exercise statement:
[tex]2x+y^2=8[/tex] [tex]y=x[/tex]Substituting y for x in the equation:
[tex]2y+y^2\\y^2+2y-8(y+4)(y-2)=8[/tex]
Analyzing the equation formed, we can see that it will have the shape of a parabola, and that the values of x will be between:
[tex]X: -4\leq y\leq 2[/tex]

what theorem can be used to probe the 2 triangles similar?
Answer:
B. SAS
Step-by-step explanation:
Two sides of ∆DEF (DE and DF) are proportional to two corresponding sides of ∆ABC (AB and AC), and also their included angles (<D and <A) are equal to each other.
Therefore, based on the SAS criterion, both triangles are proven to be similar to each other.
Both triangles satisfy the SAD Criterion, and hence, they can be proven to be similar to each other.
