Answer:
Option C) Critical value is based on the significance level and determines the boundary for the rejection region
Step-by-step explanation:
Critical Value:
- In hypothesis testing, a critical value is a point that is compared to the test statistic
- It is used to determine whether to reject the null hypothesis or accept the null hypothesis.
- If the absolute value of your test statistic is greater than the critical value,we fail to accept the null hypothesis and reject it.
- Critical value is affected by the significance level of the testing.
- It is the value that a test statistic must exceed in order for the the null hypothesis to be rejected.
Thus, option C) is the correct interpretation of critical values.
Option C) Critical value is based on the significance level and determines the boundary for the rejection region
Answer: 3.75 ft
Step-by-step explanation:
Here we are given the measure of the length of a window. Generally the length is given in the International System of units format (meters); however, in this case we are given the length in feet and inches:
Now, before converting this whole measure to feet, we have to know that , then we can perform the conversion:
This means
Hence:
This is the measure of the length of the window in feet.
Answer:
The last one
Step-by-step explanation:
In a right triangle the expression of the sin is the quotiont of the opposite side and the hypotenuse
- sin x° =
We draw region ABC. Lines that connect y = 0 and y = x³ are vertical so:
(i) prependicular to the axis x - disc method;
(ii) parallel to the axis y - shell method;
(iii) parallel to the line x = 18 - shell method.
Limits of integration for x are easy x₁ = 0 and x₂ = 9.
Now, we have all information, so we could calculate volume.
(i)
Answer B. or D.
(ii)
So we know that the correct answer is D.
(iii)
Line x = h
Answer D. just as before.
