Graham recruited student volunteers to participate in his dissertation study. He set up several times for students to come to a specified classroom and read various types of instructional materials and to be tested. He ran all of his control conditions first and then for each session he placed all students at the session in the same treatment condition. This is problematic because those who volunteered early are likely different than those who volunteered later. This problem is primarily due to 1. response bias. 2. instrumentation bias. 3. researcher bias. 4. sampling bias.
Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.

What is the y-intercept of y=2/3x+2
Answer:
(0,2)
Step-by-step explanation:
The linear equation is mx+b=y.
m=slope
x= x coordinates
b=y intercept
y=y coordinates
In this case 2 is the y intercept.
Answer:
Y-intercepts: (0,2) so I'm pretty sure your answer is 2.

If you overestimate the standard deviation of the population, which type of error are you potentially increasing
Answer:
Standard Error
Step-by-step explanation:
The standard deviation is directly proportional to the sample standard deviation or standard error.
According to the relation :
Standard Error = standard deviation / sqrt(sample size)
Going by these relation an increase in the value of standard deviation will favor or increase the standard error withba constant Number of samples.
Therefore, overestimating the standard deviation will. Cause an increase in the standard error, while underestimating the standard deviation will also lower the standard error.

A high school teacher is interested to compare the average time for students to complete a standardized test for three different classes of students. The teacher collects random data for time to complete the standardized test (in minutes) for students in three different classes and the dataset is provided below. The teacher is interested to know if the average time to complete the standardized test is statistically the same for three classes of students. Use a significance level of 5%. The teacher has confirmed that the samples were randomly selected and independent, and the populations have normal distribution and the population variances are equal. (a) calculate the Test Statistic for this example (round your answer to 2 decimal places) (b) calculate the P-value for this example (round your answer to 2 decimal places)

Monica paid sales tax of $105 when she bought a new TV. If the sales tax is 5%, what was the cost of the TV?
Answer:
$31.5
Step-by-step explanation:
X * 5% = $1.50
X = $1.50 / 5%
Or by using simple rule of three:
If 5% is $1.50
Then 100% is X
So you obtain = $30
Now you just need to sum The net prices and the taxes
Net + tax = Total Charge
$30 + $1.5 = $31.5

Which equation and solution can be used to solve this problem?
Twenty-two less than a number is twenty-four.
q + 22 = 24: Subtract 22 from both sides. The answer is 2.
24 + q = 22: Subtract 22 from both sides. The answer is 2.
q minus 24 = 22: Add 24 to both sides. The answer is 46.
q minus 22 = 24: Add 22 to both sides. The answer is 46.
Answer:
Step-by-step explanation:
22 less than a number, q-22, ‘is’ 24 is =24
q-22=24 adding 22 to both sides gives q=46
Answer:
q minus 22 = 24: Add 22 to both sides. The answer is 46.
Step-by-step explanation:
Solve each equation to see if it works.
Q - 22 = 24 does work.

On a map, 2.7 inches = 60 miles. How far apart are two cities if they measure 4.5 inches
apart on the map?
Answer:
120 miles
Step-by-step explanation:
2.7 times 2 is 4.5, so 60 times 2 is 120 (you're basically doubling both.)
Which solid has a greater volume? O A. Figure A 48 B. Figure B O C. they are equal A 2 O D. need more information
9514 1404 393
Answer:
B. Figure B
Step-by-step explanation:
The figure is difficult to read. We assume the height of the pyramid is 9, and the radius of the cylinder is 1.
The pyramid volume is ...
V = 1/3Bh
V = 1/3(4²)(9) = 48 . . . cubic units
__
The cylinder volume is ...
V = πr²h
V = π(1²)(48) = 48π . . . cubic units
The cylinder has π times as much volume as the pyramid. Figure B is larger.
_____
Additional comment
If the diameter (not the radius) of the cylinder is 1 unit, then its volume is 12π cubic units and the pyramid has more volume.

Answer:
14.333 yards
516 inches
Answer:
3) 43 ft = 14.33 yards and 516 inches.
Step-by-step explanation:
43 ft = ? yards
Divide 43 by 3: 43 ÷ 3 = 14.33 yards
43 ft = ? inches

If this figure is dilated by a scale factor of 3, what would the new coordinates be?
Answer:
J (-3,3), G (0,3), H (4,9), I (3,3)
Step-by-step explanation:
When your dilating a figuring it either gets larger or smaller. Since this is a positive number, and it is not a fraction then the figure is getting larger. Now you multiply each of the original coordinates by 3 to get the dilated coordinates.
