There are different variations in population size.  The best reason why the simulation of the sampling distribution is not approximately normal is that The sample size was not sufficiently large.

<h3>What takes place if a sample size is not big enough? </h3>
  • When a sample size taken by a person or a researcher  is not big or inadequate for the alpha level and also analyses that one have chosen to do,  it will limit the study statistical power.

Due to the above, the ability to know a statistical effect in one's sample if the effect are present in the population is greatly reduces.

See full options below

Which of the following would be the best reason why the simulation of the sampling distribution is not approximately normal?

A The samples were not selected at random.

B The sample size was not sufficiently large.

с The population distribution was approximately normal.

D The samples were selected without replacement.

E The sample means were less than the population mean.

An airplane starts at 0 feet. It rose 21,000 feet at takeoff. it then descended 4,329 feet because of clouds. An oncoming plane
sveta [45]

answer

1). Airplane is flying at 14551 feet.

2). Height of the mountain is 4299 feet.

--------------------------------------------------------------------------------------------------------------

1). An airplane starts at the level = 0 feet

It rose to the altitude = 21000 feet

It descends by the height due to clouds = 4329 feet

So the height of the airplane = 21000 - 4329

= 16671 feet

After giving pass to a plane it ascends by the height = 6333 feet

Now the height of the airplane = 16671 + 6333

= 23004 feet

Then the airplane descends again to give the pass to a airplane again.

Altitude after descending by 8453 feet = 23004 - 8453 = 14551 feet

Airplane is flying at 14551 feet.

2). Distance between the top of the mountain to the floor of the valley = 4392 feet

Valley is 93 feet below the sea level.

Therefore, the height of the mountain will be = 4392 - 93

= 4299 feet

hope this helps you

Morgarella [4.7K]

Answer:

People can spread false information and people can upload explicit, inappropriate pictures.

<em>False information</em> - Sometimes people can abuse social media by spreading rumors about people, or causing mayhem that may not be factually correct. You should look out for this and avoid it by using credible sources and checking the website credentials.

Explicit Images and Videos - People can also abuse social media platforms by posting things that are not fit for the general environment. A good rule is make choices that build others up and support them!
