In his Fourteen Points, why did President Wilson include resolutions specifically about European

Solnce55 [7]

Answer:

The correct answer is C. President Wilson included resolutions specifically about European territories in his Fourteen Points because territorial disputes among European nations were a major reason the war began in the first place.

Step-by-step explanation:

The Fourteen Points were the pacifist plan devised by President Woodrow Wilson at the end of World War I, with the aim of avoiding tensions between the former European combatants of the conflict and thus achieve a lasting peace between nations, framed in the League of Nations as supranational entity. Basically, the Fourteen Points sought to avoid the imposition of excessive sanctions on the defeated, as well as the obtaining of great benefits by the winners, so as not to break the territorial status quo prior to the war and thus avoid generating tensions in the future.

A certain flight arrives on time 8484 percent of the time. Suppose 143143 flights are randomly selected. Use the normal approxim

Troyanec [42]

Answer:

a) P(x=108)=0.0020

b) P(x≥108)=0.9980

c) P(x<124)=0.7794

d) P(124≤x≤128)=0.1925

Step-by-step explanation:

We know the population proportion, that is p=0.84.

We take a sample of size n=143.

We will use the normal approximation to the binomial distribution to model this problem.

The mean and standard deviation of the normal approximation to the binomial distribution will be:

$\mu=np=143*0.84=120.12\\\\\sigma=\sqrt{np(1-p)}=\sqrt{143*0.84*0.16}=\sqrt{19.22}=4.38$

a) We have to calculate the probability that exactly 108 flights are on time.

As the normal distribution considers the random variable to be continous, we have to apply the continuity correction factor.

In this case, the probability of 108 flights on time can be calculated as P(107.5<x<108.5):

$P(x=108)=P(107.5$

b) Now we have to calculate that at least 108 flights are on time.

As the probability includes 108, the continuity factor will indicates that we calculate P(x>107.5). The z-value for x=107.5 has been already calculated in point a:

$P(x\geq108)=P(x>107.5)=P(z>-2.88)=0.9980$

c) We have to calculate the probability that fewer than 124 flights are on time. According to the continuity factor, we have to calculate the probability P(x<123.5), as the flight number 124 is not included in the interval.

$P(x$
