We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif

Gala2k [10]

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

Answer:

$m\angle FAD =42^o$

Step-by-step explanation:

<u>Right Triangles</u>

Right triangles are those who have a right angle, i.e. 90°. The other two angles must sum 90° to complete the 180° which must sum the internal angles of a triangle.

The image shows a circle with two similar triangles FAD and EAD. We know they are congruent because they share the same height and have a base of the same value (as indicated by the ticks). The segment AD must be perpendicular to FE since it comes from the center of the circle. We can conclude $\angle FDA$ is right, i.e. measures 90°.
