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 second option: The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
As seen on the graph, we are given the points (20,12) and (35,21).
This means that at 20mi driven, the amount paid is $12, and at 35mi driven, the amount is $21.
To find the rate of change we divide the distance driven by the cost to find the cost per mile:
20/12 = 0.6
35/21 = 0.6
The slope is 0.6, so it costs an extra $0.6 for every mi driven. Therefore it is the second option: The amount a customer pays increases $0.60 per mile driven.
Hope this helped!
5.6(4 + p) You need the parentheses to show that you are multiplying by the sum.
Answer:
8x10^-7
Step-by-step explanation:
First one you have correct however the second one you were close lets figure it out:
0.0000008
In order to move the decimal in front of the eight we have to "jump" 7 times to the right. Furthermore since we have to move the decimal to the right our exponent will be negative. That means that we have:
