Answer:
In this case, as the null hypothesis is not rejected, the only error possible is Type II error. That means that the researchers conclude that the students are not fluent when they really are fluent in English.
Step-by-step explanation:
They test an hypothesis to test the claim that students are strong in english.
The null and alternative hypothesis are:
If they reject the null hypothesis, that means that the studens are fluent in English.
With the data they have, they conclude that the evidence is not strong enough to conclude that the students are fluent in English.
That means they failed to reject the null hypothesis.
The type of errors are:
Type I error: reject a true null hypothesis.
Type II error: failed to reject a false null hypothesis.
In this case, as the null hypothesis is not rejected, the only error possible is Type II error. That means that the researchers conclude that the students are not fluent when they really are fluent in English.
Answer: 28 feet.
Step-by-step explanation:

Answer:
or 0.0025 0r 0.25%
Step-by-step explanation:
There are three categories that will get a prize
1) First place = 1 person
2) Second place = 5 persons
3) Third place = 20 persons
A total of 26 people will get prizes.
However, we want to determine your chance to win one of the second place prizes
There are 5 prizes in second place
This means out of a total of 2000 people, you could be among the 5
i.e 5 out of 2000
This is
This means you have a chance of 1 out of 400
= 0.25%
