Option B) Reject null hypothesis

Step-by-step explanation:

We are given the following in the question:

We are given the null hypothesis:

H_0 = 4,000

$\alpha = 0.01$

$z_{stat} = 6.00$

Two tailed z-test

Now, $z_{critical} \text{ at 0.01 level of significance } = \pm 2.58$

Since,

The calculated z-statistic does not lie in the acceptance region, we fail to accept and reject the null hypothesis.

Left-tailed z-test

Now, $z_{critical} \text{ at 0.01 level of significance } = -2.58$

Since,

$z_{stat} z_{critical}$

We fail to accept and reject the null hypothesis.

Right-tailed z-test

Now, $z_{critical} \text{ at 0.01 level of significance } = 2.58$

Since,

$z_{stat} z_{critical}$

We fail to accept and reject the null hypothesis.

Step-by-step explanation:

F - g + h

(10 - 5 + 1)

10 - 5 = 5

5 + 1 = 6
