ludmilkaskok [199]

Answer:

The lower bound of the probability that there will be between 100 and 140 passengers 96%.

Step-by-step explanation:

The Chebyshev's theorem states that, the probability that X is within k standard deviation of mean is given by,

$P(|X-\mu|$

Here, k is any positive number.

The given information is:

Mean (µ) = 120

Standard deviation (σ) = 16.

Then, we need to compute, P (100 ≤ X ≤ 140).

Then,

$\frac{Upper-\mu}{\sigma}=\frac{140-120}{\sqrt{16}}=5$

$\frac{\mu-Lower}{\sigma}=\frac{120-100}{\sqrt{16}}=5$

Since, these two values coincide it implies that the event (66000, 78000) is centered about the mean.

Also, the event P (100 ≤ X ≤ 140) is equivalent to having X within 5 standard deviation of the mean.

That is, k = 5.

Then for k = 5,

$1-\frac{1}{k^{2}}=1-\frac{1}{25}=\frac{24}{25}=0.96$

That is, P (100 ≤ X ≤ 140) ≤ 0.96 .

Thus, the lower bound of the probability that there will be between 100 and 140 passengers 96%.

Phoenix [80]

Answer:

The case is in the deliberation phase, and the jury selection will follow.

Step-by-step explanation:

As you may already know, a jury is a court with the active and influential participation of citizens who have been called upon to decide whether a defendant is guilty or not of the crimes being accused. Generally, the jury is summoned for crimes that offered someone life risks.

The citizens chosen to represent the jury will be selected shortly after the decision-making phase. The selection of the jury allows defense and prosecution attorneys to question the reason why each citizen was selected.
