Tourism & Hospitality Management QUESTION #1645

Question 6

The Sports and Adventure Tourism course classifies adventure activities into three categories based on the environment in which they take place. Which classification is correctly identified in the curriculum?

Hard adventures, soft adventures, and extreme adventures
Land adventures, Water/aqua adventures, and Aerial adventures✔️

CISA QUESTION #1774

Question 7

Which type of evidence sampling technique involves examining 100 percent of available items?

Attribute
Stop-and-go
Cell
Discovery✔️

Correct Answer Logic:

Discovery sampling is deployed when fraud is suspected or when the likelihood of locating relevant evidence is low. Its goal is to examine as close to 100 percent of the population as possible to ensure that no evidence of irregularity is overlooked. Other sampling types are used in standard compliance testing.

Agronomy QUESTION #2073

Question 8

The Blaney-Criddle method of estimating crop water requirements is primarily based on:

Net solar radiation and wind speed data
Mean monthly temperature and daylight hours (sunshine percentage), making it suitable for regions where only temperature data are available but less accurate than the Penman-Monteith method✔️
Actual measured pan evaporation data corrected by a pan coefficient
Soil type and available water capacity in the root zone

Correct Answer Logic:

The Blaney-Criddle formula $ET = p(0.46T + 8)$ uses only mean monthly temperature (T) and monthly percentage of annual daylight hours (p). It was widely used before reliable radiation and humidity data were available. While simple, it overestimates ET in humid conditions and underestimates in arid climates — less accurate than the Penman-Monteith equation.

Statistics QUESTION #1990

Question 19

For the Poisson distribution with parameter $\lambda$, which of the following statements is INCORRECT?

Mean = Variance = $\lambda$
The distribution is always positively skewed for finite $\lambda$
The mgf is $M(t) = e^{\lambda(e^t - 1)}$
As $\lambda \to \infty$, the Poisson distribution approaches the t-distribution✔️

Correct Answer Logic:

The mean, variance, and mgf statements are all correct properties of the Poisson distribution. As $\lambda \to \infty$, the Poisson distribution approaches the NORMAL distribution (not the t-distribution), by the Central Limit Theorem. This is what makes statement (D) incorrect.

Mathematics QUESTION #1332

Question 20

For a parabola $y^2=4ax$, the latus rectum is the chord through the focus perpendicular to the axis. Its $x$-coordinate is:

$a$✔️
$2a$
$4a$

Correct Answer Logic:

For the parabola $y^2=4ax$, the focus is at $(a,0)$. The latus rectum is the vertical chord through the focus, so it is at $x=a$. The arc from vertex $(0,0)$ to the latus rectum end ($x=a$) is used to find the center of mass of the corresponding surface of revolution.
