Answer:
C: A randomized block design experiment
Step-by-step explanation:
We are told the participants are divided by gender into groups which we can call blocks. Then, within each group, they are randomly assigned to either the treatment or control group. This means they are assigned treatments within each block.
A randomized block design is defined as an experimental design whereby the experimental units are divided into groups which we call blocks. After that treatments will be randomly assigned to the experimental units within each of the blocks.
Thus, this corresponds with our question and we can say it's a randomized block design experiment.
Use the drop-down menus to label the points on the number line.
Answer:
Step-by-Use the drop-down menus to label the points on the number line.
Point A is at . - 1 2/4
Point B is at . - 3/4
Point C is at 3/4.
Point D is at explanation:1 3/4
The position of the points A, B, C, and D on the number line will be –3/2, –3/4, 3/4, and 7/4.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space.
The number line is shown below.
From the figure, we can observe that there are 4 sections between each successive numbers.
The point A is at –1 2/4 that is –3/2.
The point B is at –3/4.
Then the point C is at 3/4.
And the point D is at 1 3/4 that is 7/4.

The dispersion among sample means is less than the dispersion among the sampled items themselves becausea:______
a. Each sample is smaller than population
b. Very large value are averaged down
c. Sampled items are all drawn from the same population
d. None of thesee.
e. b and c
Answer:
The dispersion among sample means is less than the dispersion among the sampled items themselves because:______
b. Very large values are averaged down
Step-by-step explanation:
The sample means represent average values obtained from both large and moderate values. Through the process of averaging, the data values obtained as the sample means are much closer to the true values. This is why the dispersions among the sampled items will be larger than the dispersions among the sample means. Sample dispersions describe how spread out the data values are on the number line.

3) The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38.
Answer:
1.66
Step-by-step explanation:
The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38
Given that :
Mean (m) = 4.68
Standard deviation (s) = 2.83
Value of x = 9.38
Zscore = (x - mean) / standard deviation
Zscore = (9.38 - 4.68) / 2.83
Zscore = 4.7 / 2.83
Zscore = 1.6607773
Hence, Zscore for a value of 9.38 is 1.66

classify which numbers are rational or irrational
The given numbers are:
5/4
√100
7.3
0.00247
√4/9
√2/24
0.01 with the line above the 1
Answer:
5/4 = rational √100 = rational 7.3 =rational 0.00247 = rational √4/9 = irrational √2/24 = irrational 0.01 (with the line) = irrational
Step-by-step explanation:
an irrational number is an infinitely repeating number that can not be written as a fraction, instead it must be written as a decimal. A rational number is a number that can be made by dividing two integers (an integer is a number with no fractional part).
The numbers are,
a. 5/4 = Rational
b. √100 = Rational
c. 7.3 = Rational
d. 0.00247 = Rational
e. √4/9 = Irrational
f. √2/24 = Irrational
g. 0.01 (with the line above the 1) = Irrational
What is Number system?
A system of writing to express the number is called number system.
Given that;
The numbers are,
5/4, √100 , 7.3 , 0.00247, √4/9 , √2/24 , 0.01 with the line above the 1.
Now,
Check the numbers as;
5/4 = 1.25
So, The number is a Rational number.
√100 = 10
So, The number is a Rational number.
7.3 = 7.3
So, The number is a Rational number.
0.00247 = 247/100000
So, The number is a Rational number.
√4/9 = 2/3 = 0.666.......
So, The number is a Irrational number.
√2/24
So, The number is a Irrational number.
0.01 with the line above the 1
So, The number is a Irrational number.
Thus, The numbers are,
a. 5/4 = Rational
b. √100 = Rational
c. 7.3 = Rational
d. 0.00247 = Rational
e. √4/9 = Rational
f. √2/24 = Irrational
g. 0.01 (with the line above the 1) = Irrational
