Answer:
Option D) Reject the claim that the proportion of Americans that have seen a UFO is equal to 5 in a thousand when that proportion is actually 5 in a thousand.
Step-by-step explanation:
We are given the following information:
A hypothesis test to support the given claim that the proportion of Americans that have seen a UFO is less than 5 in a thousand.
Type I error:
- Type I error is the rejection of a true null hypothesis that is we reject the null hypothesis given it is true.
- It is also known as a false positive.
First, we design the null and the alternate hypothesis
Thus, for the given hypothesis test, we describe type I error as:
Option D) Reject the claim that the proportion of Americans that have seen a UFO is equal to 5 in a thousand when that proportion is actually 5 in a thousand.
(I'm going to translate y' to dy/dx as it makes it easier to read for me, you could change it back if you wanted.)
(separate the variables)
(by letting c = ln k and using log laws)
(raise everything to power e)
(applying boundary conditions)

<u>Trigonometric Formulas</u>
To solve this problem, we must recall some basic relations and concepts.
The main trigonometric identity relates the sine to the cosine:
The tangent can be found by
The cosine and the secant are related by
They both have the same sign.
The sine is positive in the first and second quadrants, the cosine is positive in the first and fourth quadrants.
The sine is negative in the third and fourth quadrants, the cosine is negative in the second and third quadrants.
We are given
Find the cosine by solving
We have placed the negative sign because we know the secant ('sex') is negative and they both have the same sign.
Now compute the tangent
