Answer:
option A
Step-by-step explanation:
To Test
H₀ : μ = 3.75
H₁ : μ ≠ 3.75
now,
If μ = 3.95 then it means H₀ is not true.
then the probability is rejecting the null hypothesis.
Hence, the probability is the power of the test against the alternative μ=3.95
The correct answer is option A
When a straight line is given the form:

m is the gradient. It shows how the value of y changes for an increase of x by 1.
So, in this case, the gradient is

We can use the arc length formula to solve this.
Arc length = 
Given arc length is 7 and radius is 5, we can plug in the values and solve for q.

ANSWER:
We can use the equation
to find the value of q. And, the value of q is 80.21°.
