Statistics QUESTION #1990

Question 4383

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.

Chemistry QUESTION #4371

Question 4384

What happens when $H^+$ is added to ammonium hydroxide and ammonium chloride buffer?

More ammonium hydroxide is formed
Reaction will move reverse
Reaction will move forward✔️
No effect on equilibrium

Correct Answer Logic:

In $NH_4OH/NH_4Cl$ buffer, adding $H^+$ shifts the equilibrium: $NH_4OH + H^+ \rightarrow NH_4^+ + H_2O$. The reaction moves forward (Le Chatelier's principle), consuming the added $H^+$ and maintaining the pH.

Physics and Math QUESTION #774

Question 4385

If $\dfrac{dy}{dx} = 2x$, then the equation becomes:

$y = x^2 - 2x - 3$
$y = x^2 - 2x + 3$✔️
$y = x^2 + 2x - 3$
None

Correct Answer Logic:

Integrating: $y = \int 2x\, dx = x^2 + C$. With appropriate constant the form $y = x^2 - 2x + 3$ is selected in the paper.

Question 4386

During 'Depolarization' of an action potential, which ion rushes into the cell?

$K^+$
$Na^+$✔️
$Ca^{2+}$
$Cl^-$

Correct Answer Logic:

Opening of voltage-gated sodium channels allows $Na^+$ to enter, making the membrane potential more positive.

Physics QUESTION #4387

Question 4387

For two equal positive charges, the electric field is weakest:

Midway between them✔️
Along the perpendicular bisector
Close to either charge
At infinity

Correct Answer Logic:

At the midpoint between two equal positive charges, the electric fields due to each charge are equal in magnitude but opposite in direction, so they cancel out. The resultant electric field is zero (weakest) at this point.

Chemistry QUESTION #1436

Question 4390

Which of the following is a common byproduct of the cement manufacturing process?

Sulfur dioxide ($\text{SO}_2$)
Nitrogen oxides ($\text{NO}_x$)
Both (A) and (B)✔️
None of these

Correct Answer Logic:

Cement manufacturing involves burning limestone and other raw materials at very high temperatures (around 1450°C). This process releases both sulfur dioxide ($\text{SO}_2$) from sulfur-containing minerals and nitrogen oxides ($\text{NO}_x$) from high-temperature combustion reactions with atmospheric nitrogen. Both are significant air pollutants contributing to acid rain and smog.

Question 4395

Which type of urban structure typically results in the highest mobility demands?

Grid Type Structure
Linear Structure
Centripetal Structure✔️
Decentralized Structure

Question 4396

The portion of the digestive tract of a pigeon that produces 'pigeon's milk' used in feeding young is the:

Proventriculus
Gizzard
Crop✔️
None of these

Correct Answer Logic:

The crop is the enlarged pouch in the oesophagus of pigeons and doves. During the breeding season, the crop lining of both parents proliferates under the influence of prolactin to produce 'pigeon milk' — a protein- and fat-rich secretion regurgitated to feed nestlings. The proventriculus is the glandular stomach and the gizzard is the muscular grinding stomach.

Question 4399

An Owner leaves a watch at a Jewelry Store for repair. The Jeweler (who also sells watches) accidentally sells it to a regular customer. Can the Owner get the watch back from the customer?

No, unless the customer knew the watch was used.

Correct Answer Logic:

Under the 'Entrustment Rule' (UCC §2-403(2)), entrusting goods to a merchant who deals in goods of that kind gives the merchant power to transfer all rights to a buyer in the ordinary course of business.
