The examples of construct that the research test can be measuring include:
How often does one make eye contact with others?Do you prefer having a smaller group of friends or larger group?What is construct validity?It should be noted that construct validity simply means the extent to which a test accurately assesses what it's meant to assess.
The way to improve the test is to ensure that the measurements and indicators are carefully developed based on the existing knowledge.
The method of estimating reliability that would be used for the test is the split-half method. This is important as it assesses the internal consistency of a test.
The examples of error that can be witnessed on the test include procedural error, environmental error, and human error.
Lastly, trait error is the error that is attributed to the individual which brings about the difference between the true and observed scores while method error is the error that occurs in measurement such that the value obtained is different from the actual value.

The sample proportion is given as 5.
Calculations and ParametersTo solve for the sample proportion:
The sample proportion is denoted by
[tex]p= \frac{y}{n}[/tex]
Where,
y: is the number of observations that possess some special characteristic
n: is the total number of observations in the sample.
We have the following info:

sampling.
his sample. This is an example of
OA. systematic
B. quota
C. random
D. cluster
Answer:
A. Systematic
Explanation:
it is because he ask each student in that particular class, so that he question them in a systematic way.
A multiple-choice test consists of 8 questions. Each question has answer choices of a, b, c, d, and e, and only one of the choices is correct. If a student randomly guesses on each question, what is the probability that he gets fewer than 3 of them correct?
Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.
The probability that he gets fewer than 3 of them correct is : 0.80
Analysis of the problemThe problem is a Binomial problem
n = 8
P(correct ) = 1/5
Determine the probability that a student gets fewer than 3 correct answersP( 0<= x <=2 ) = binomcdf ( 8, 1/5, 2)
= ⁸C₂(1/5)² (4/5)⁶ + ⁸C₁(1/5)(4/5)⁷ + ⁸C₀(4/5)⁸
= 0.7969 ≈ 0.80
Hence we can conclude that The probability that he gets fewer than 3 of them correct is : 0.80

A) -3
B) -1
C) 3
D) 6
The value of f(2p), given that f(2) = 5 and p is a constant is -3 (option A)
How to determine the value of f(2p)?First, we shall obtain the value of p. Details below:

p = 2 - 5
= -3
Finally, we shall obtain the value of f(2p). Details below:
Function: f(x) = x - pp = constant = -3Value of f(2p) =?f(x) = x - p
But
x = 2p
f(2p) = 2p - p
f(2p) = p

Describe two of the four types of project shut down and explain how they work from start to finish. Under what circumstances do you think these two types of project shut down might be used?
There are four different forms of project shut down that can occur when there is no longer a need to continue a project, they are:
ExtinctionAdditionIntegrationStarvationLet's choose extinction and starvation to explain in more detail. Upon extinction, the project is terminated because it was correctly developed and delivered, fulfilling the objectives set at the beginning.
In the case of starvation, the project is not literally closed, but suffers from budget cuts, harming the objectives established at the beginning, and may compromise the entire progress of the project.
How important is project management?It is essential for the objectives stipulated at the beginning of a project to be effectively accomplished, within the stipulated time and budget. Project management assists in direction and productivity along the project path, reducing risk and increasing control at every step.
Therefore, it is essential that there is a management aligned with the objectives, making the closure of projects occur in a planned way, with the objectives fulfilled and the total quality achieved.

A packaging company has an old machine which improperly packages 30% of all its goods. The company has a special order to package 20 products for a client. Based on Chebyshev's theorem we can be 89% sure that between ____ and ____ of the products will be improperly packaged.
Answer:
0,12
Explanation:
none
Based on Chebyshev's theorem we can be 89% sure that between 0 and 12 of the products will be improperly packaged.
What is probability?The chance of happening an event out of all the possible outcomes is called the probability of an event.
A packaging company has an old machine which improperly packages 30% of all its goods. The company has a special order to package 20 products for a client.
The probability that goods are improperly packaged is 0.30 and sample size is 20.
Then, μ = 20 x 0.30 =6
standard deviation, σ = √ [np(1-p)]
Put the values, we get
σ = 2.05
The value of k can be
1-1/k² = 0.89
Solving the expression for k, we get
k = 3.01
Based on Chebyshev's theorem, the limit are
μ ± kσ = (μ - kσ , μ + kσ )
={(6 - (3.01 x 2.05)) , (6 + (3.01 x 2.05)) }
={0,12}
Thus, we can be 89% sure that between 0 and 12 of the products will be improperly packaged.

ARP stands for ______.
Answer:
Address Resolution Protocol
Explanation:
ARP is a protocol that helps devices on a network find each other by translating IP addresses into MAC addresses.
ARP stands for Address Resolution Protocol. It is a communication protocol used in computer networks to translate an IP (Internet Protocol) address into a MAC (Media Access Control) address.
In simpler terms, it helps devices on a network to find each other and establish a connection.
When a device wants to send data to another device, it needs to know the MAC address of the recipient.
ARP allows the device to find the MAC address by sending out a broadcast message to all devices on the network, asking "Who has this IP address?".
The device with the matching IP address responds with its MAC address, allowing the sender to establish communication.
