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:
The area is 17,388 feet.
Step-by-step explanation:
First, you have to do 34.5 x 6 and then 14 x 6 which should get you 207 and 84. Next, all you have to do is multiply 207 by 84 and get your answer. Hope this helped : )
Answer:
They are parallel
Step-by-step explanation:
They both start with y=2/3x so you know the slope is the same. The +4 and -1 are just the intercepts
Answer:
-2 ≤ x ≤ 4
Step-by-step explanation:
|2x - 2| ≤ 6
2x - 2 ≤ 6 or 2x - 2 ≥ -6
2x - 2 ≤ 6
2x ≤ 8
x ≤ 4
2x - 2 ≥ -6
2x ≥ -4
x ≥ -2
