Statistics QUESTION #1982

Question 6002

The partial correlation coefficient $r_{12.3}$ between $X_1$ and $X_2$ after eliminating the linear effect of $X_3$ is computed as the simple correlation between:

$X_1$ and $X_2$ directly
The residuals $X_{1.3}$ and $X_{2.3}$ from their respective regressions on $X_3$✔️
The standardized values of $X_1$ and $X_2$
The ranked values of $X_1$ and $X_2$

Correct Answer Logic:

The partial correlation $r_{12.3}$ is defined as the Pearson correlation between the residuals $X_{1.3} = X_1 - \hat{X}_{1|X_3}$ and $X_{2.3} = X_2 - \hat{X}_{2|X_3}$. This removes the linear influence of $X_3$ from both $X_1$ and $X_2$ before computing their correlation.

Mathematics QUESTION #7444

Question 6003

The mean of the data set comprising of 16 observations is 16. If one of the observations valued 16 is deleted and three new observations valued 3, 4 and 5 are added to the data, then the mean of the resultant data is:

16.8
16
15.8
14✔️

Correct Answer Logic:

Original sum = $16 \times 16 = 256$. After deleting 16: new sum = $256 - 16 = 240$. After adding 3, 4, 5: new sum = $240 + 3 + 4 + 5 = 252$. Number of observations = $16 - 1 + 3 = 18$. New mean = $\frac{252}{18} = 14$.

Physics QUESTION #7838

Question 6004

Force on a positive charge q moving with velocity v in magnetic field B is:

$q = Fv \times B$
$F = qv \times B$✔️

CISA QUESTION #1769

Question 6005

Which of the following statements about a control self-assessment (CSA) is INCORRECT?

It empowers users to take ownership and accountability for controls
It can replace the need for a traditional audit✔️
It may be used to flag high-risk areas for subsequent review
It lacks the level of independence offered by an external auditor

Correct Answer Logic:

A CSA is a valuable internal tool that promotes user accountability and can identify areas warranting deeper review. However, it is not a substitute for a traditional independent audit, as it does not carry the same level of independence or rigor required for formal audit conclusions.

Dairy Food Science and Technology QUESTION #5947

Question 6008

In spray drying, the glass transition temperature ($T_g$) of milk powder is critical because:

Below $T_g$, the powder is in a rubbery state and flows freely
Above $T_g$, amorphous lactose transitions from glassy (stable) to rubbery (sticky, prone to caking and collapse), reducing powder quality✔️
$T_g$ determines the fat melting point in powder
$T_g$ affects the solubility of casein in reconstituted powder

Correct Answer Logic:

Below $T_g$, amorphous lactose is in a glassy rigid state — stable. Above $T_g$ (lowered by moisture content), lactose enters a rubbery state: high molecular mobility, sticky surface, particle caking, and potential collapse of the powder structure. Keeping powder moisture $<3\text{–}4\%$ maintains $T_g$ well above ambient storage temperatures.

Physics QUESTION #7230

Question 6009

If force ($F$), velocity ($V$), and time ($T$) are taken as fundamental units, then the dimensions of mass in this system are:

$[FV^{-1}T^{-1}]$
$[FV^{-1}T^{1}]$
$[FVT^{-1}]$
$[FV^{-1}T]$✔️

Correct Answer Logic:

From Newton's second law: $F = ma = m\dfrac{v}{t}$

So $m = \dfrac{Ft}{v}$

In terms of fundamental units F, V, T:

$[m] = \dfrac{[F][T]}{[V]} = FV^{-1}T$

Question 6010

$18\tfrac{1}{6} \div 2\tfrac{1}{3} = ?$

$4\tfrac{1}{2}$
$11\tfrac{7}{14}$
$7\tfrac{11}{14}$✔️
None

Correct Answer Logic:

$18\tfrac{1}{6} = \dfrac{109}{6}$ and $2\tfrac{1}{3} = \dfrac{7}{3}$
$\dfrac{109}{6} \div \dfrac{7}{3} = \dfrac{109}{6} \times \dfrac{3}{7} = \dfrac{327}{42} = \dfrac{109}{14} = 7\tfrac{11}{14}$

Negotiating wages
Securing vital installations✔️
Arresting all strikers
Leaving the terminal

Correct Answer Logic:

Per Section 6, the ASF's duty is the security of installations and aerodromes, regardless of labor disputes.

Question 6012

Under Section 3(3) added by Act No. IX of 2016, when a civil servant of a devolved Ministry is transferred to a Province under the Eighteenth Amendment, on what terms and conditions does he become a provincial civil servant?

On terms and conditions as may be determined by the Provincial Government
On terms and conditions as may be prescribed by the Federal Government
On the same terms and conditions as were applicable to him before such transfer✔️
On terms and conditions to be negotiated between the Federal and Provincial Governments

Correct Answer Logic:

Section 3(3) specifically provides that when a civil servant of a devolved Ministry or Division working in an Attached Department or Subordinate Office situated in a Province is transferred to that Province, he shall become a civil servant of the respective Province on the same terms and conditions of service as were applicable to him before such transfer.

Question 6015

Why is 'Cold Compression' used for extracting Lemon Oil rather than Steam Distillation?

Cold compression is cheaper
Lemon oil is a solid
Lemon oil doesn't evaporate

Correct Answer Logic:

Many citrus oils are obtained by expression (pressing) to preserve their fresh quality.

Physics QUESTION #1000

Question 6016

For a diatomic gas, $\gamma_1 = \left(\dfrac{C_p}{C_v}\right)$ for rigid molecules and $\gamma_2 = \left(\dfrac{C_p}{C_v}\right)$ for non-rigid diatomic molecules (with vibrational modes). Then which is correct?

$\gamma_2 = \gamma_1$
$2\gamma_2 = \gamma_1$
$\gamma_2 < \gamma_1$✔️
$\gamma_2 > \gamma_1$

Correct Answer Logic:

For rigid diatomic: $C_v = \frac{5}{2}R$, $\gamma_1 = \frac{7}{5} = 1.4$. With vibrational modes: $C_v = \frac{7}{2}R$, $\gamma_2 = \frac{9}{7} \approx 1.286$. Since adding vibrational modes increases $C_v$ more than $C_p$, $\gamma_2 < \gamma_1$.

The Balmer series of hydrogen spectrum appears in the:

Infrared region
Ultraviolet region
X-ray region

Question 6018

Exopolysaccharides (EPS) produced by certain yoghurt starter strains contribute to:

Syneresis prevention and improved texture (ropy/viscous yoghurt) by forming a polymer network that binds water✔️
Acidification rate and lactic acid production
Color development (white appearance)
Antimicrobial activity against pathogens

Correct Answer Logic:

EPS-producing strains of $S.\;thermophilus$ and $L.\;bulgaricus$ produce polysaccharides that interact with the protein network, increasing viscosity, reducing syneresis, and giving a ropy texture. EPS-positive strains are preferred in stirred yoghurt.

Journalism / Mass Communication QUESTION #6396

Question 6019

The Four-Step Public Relations process uses SWOT analysis in its first step. What does the acronym SWOT stand for?

Strategy, Weaknesses, Opportunities, Tactics
Strengths, Weaknesses, Opportunities, Threats✔️
Speed, Width, Outreach, Timing
Scope, Workforce, Output, Target

Correct Answer Logic:

SWOT Analysis stands for: Strengths, Weaknesses, Opportunities, Threats. It is a strategic planning tool used as part of the situational analysis in the first step of the PR process (“Defining PR Problems”). In the PR context:

Strengths: Internal positive factors — what the organisation does well
Weaknesses: Internal negative factors — areas of improvement needed
Opportunities: External positive factors — favourable trends or situations the organisation can exploit
Threats: External negative factors — risks from competitors, regulations, or public perception

The SWOT analysis is the diagnostic foundation of the PR campaign. Without understanding the current situation comprehensively, the subsequent strategy, implementation, and evaluation steps cannot be done effectively. SWOT was originally developed as a general business strategy tool and has been widely adopted across public relations, marketing, and management.

Question 6020

What does 'subtle' most likely mean in the sentence: 'The detective noticed a subtle change in the suspect's tone...'

Dramatic
Notable
Obvious
Slight✔️

Correct Answer Logic:

'Subtle' means so slight or delicate as to be difficult to notice. In this context, the detective noticed a small, not obvious change. 'Slight' is the best synonym among the options.
