Solving the given equation, the value of v that makes the statement true is:

A. v = 8.

<h3>What is the given equation?</h3>

The equation is:

$12 = 12 + \frac{v - 8}{2}$

Hence:

$\frac{v - 8}{2} = 0$

Applying cross multiplication:

v - 8 = 0

v = 8.

Hence option A is correct.

Answer:

$H_0:\mu =45\\\\H_a:\mu\geq 45$

Step-by-step explanation:

Since we have given that

A toy manufacturer claims that the mean time that its top-selling toy captures children's attention is at least 45 minutes.

Since we need to carry out a hypothesis test whether he can refute the claim.

We always take the alternate hypothesis such that it should satisfy the given statement.

And the null hypothesis can be equal to mean or other than that is given in alternate hypothesis.

So, hypothesis :

$H_0:\mu =45\\\\H_a:\mu\geq 45$
