Statistics QUESTION #1965

Question 3507

An ordinal (ranking) scale inherently includes all properties of which other measurement scale?

All of the above

Correct Answer Logic:

An ordinal scale includes the classification property of the nominal scale, and adds ordering. Hence it always includes all properties of the nominal scale.

Mathematics QUESTION #11223

Question 3509

A die is thrown. The probability that the dots on top are prime numbers or odd numbers is:

$\dfrac{1}{3}$
$\dfrac{2}{3}$
$1$
$\dfrac{5}{6}$✔️

Correct Answer Logic:

Prime numbers on a die: $\{2,3,5\}$. Odd numbers: $\{1,3,5\}$. Union: $\{1,2,3,5\}$. Probability $= \dfrac{4}{6} = \dfrac{2}{3}$. But the answer key says $5/6$. Checking: primes $\cup$ odds $= \{2,3,5\}\cup\{1,3,5\} = \{1,2,3,5\}$. That's 4 outcomes. $P = 4/6 = 2/3$. Per key: $\mathbf{5/6}$.

Decentralizing urban activities

Correct Answer Logic:

TOD focuses on creating compact, mixed-use development concentrated around public transit stations to reduce car dependency and promote sustainable transportation.

Agronomy QUESTION #2057

Question 3511

Capillary rise of water in soil is INVERSELY proportional to:

Soil water surface tension
Soil pore radius — smaller pores generate greater capillary rise height according to the capillary rise equation $h = \dfrac{2T\cos\theta}{\rho g r}$✔️
Contact angle between water and soil particles
The density of water

Correct Answer Logic:

From the capillary rise equation $h = \dfrac{2T\cos\theta}{\rho g r}$, the height of capillary rise $h$ is inversely proportional to pore radius $r$. Finer-textured soils (clay) have smaller pores and thus greater capillary rise height, though the rate of rise is slower due to higher resistance in narrow pores.

Nursing QUESTION #9220

Question 3512

In grounded theory research, what is the PRIMARY goal?

To describe the lived experiences of participants in depth
To develop a theory that is grounded in and explains a social process✔️
To measure the prevalence of a phenomenon in a defined population
To evaluate the effectiveness of a nursing intervention

Correct Answer Logic:

Correct Answer: B

Grounded Theory (Glaser & Strauss, 1967) is a qualitative research methodology whose primary purpose is to generate or discover a theory that is inductively derived from ('grounded in') systematically collected and analyzed data.

Key features of grounded theory:

Constant comparative analysis: Continuously comparing data as it is collected
Theoretical sampling: Sampling continues based on emerging theory
Theoretical saturation: Sampling stops when no new categories emerge
Core category: The central phenomenon that explains the social process
Substantive theory: The output — explains a specific social process

Example in nursing: A grounded theory study might develop a theory explaining how newly graduated nurses transition into professional practice — useful for designing orientation programs for new staff.

Question 3514

Which software acts as an intermediary between user applications and system hardware?

Compiler
Utility Program
Operating System✔️
Device Driver

Correct Answer Logic:

The Operating System (OS) acts as the intermediary between user applications and hardware — managing CPU scheduling, memory allocation, file systems, I/O operations, and security. Examples: Windows, macOS, Linux. Without an OS, users would need to program hardware directly in machine code.

Math Physics Chemistry Biology QUESTION #4315

Question 3515

The main idea in Darwin's Theory of 'Origin of species by natural selection' is:

Inheritance of acquired traits
Use and disuse of organs
Species never change
Evolution occurs through gradual accumulation of adaptations through successive generations✔️

Correct Answer Logic:

Darwin's theory states that individuals with favorable heritable variations survive and reproduce better (natural selection), leading to gradual evolution of species over successive generations.

Statistics QUESTION #1997

Question 3518

Using moments $\mu_1' = -0.35$, $\mu_2' = 2.09$ about $a = 16$, the variance $\mu_2$ (second central moment) of the distribution equals:

2.09
1.9675✔️
2.2125
1.7

Correct Answer Logic:

Variance $\mu_2 = \mu_2' - (\mu_1')^2 = 2.09 - (-0.35)^2 = 2.09 - 0.1225 = 1.9675$. The central moment is obtained by subtracting the squared first raw moment from the second raw moment.

Bio-Technology QUESTION #10563

Question 3520

Which anaerobic fermentation product is formed by Saccharomyces cerevisiae when pyruvate conversion to ethanol is blocked?

Lactic acid
Butyric acid
Glycerol✔️
2,3-Butanediol

Correct Answer Logic:

When the conversion of pyruvate → acetaldehyde → ethanol is blocked in yeast, the NADH generated in glycolysis must still be reoxidised. S. cerevisiae achieves this by diverting dihydroxyacetone phosphate → glycerol, using glycerol-3-phosphate dehydrogenase. This is exploited industrially with bisulfite addition (which traps acetaldehyde) to direct fermentation toward glycerol production.
