Arisa [49]

If F(x, y, z) = i + sin(z) j + y cos(z) k is conservative, then there exists a scalar function f(x, y, z) such that grad(f) = F, which means

∂f/∂x = 1

∂f/∂y = sin(z)

∂f/∂z = y cos(z)

Integrating each each of these equations gives

∫ ∂f/∂x dx = ∫ dx ⇒ f(x, y, z) = x + α(y, z)

∫ ∂f/∂y dy = ∫ sin(z) dy ⇒ f(x, y, z) = y sin(z) + β(x, z)

∫ ∂f/∂z dx = ∫ y cos(z) dz ⇒ f(x, y, z) = y sin(z) + γ(x, y)

It follows that α(y, z) = y sin(z) and β(x, z) + γ(x, y) = x + C where C is a constant. So

f(x, y, z) = x + y sin(z) + C

and F is indeed conservative.

Considering the p-value of 0.6, the decision is that we do not reject the null hypothesis.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, we test if the proportions are equal, that is:

$H_0: p_g = p_k$

At the alternative hypothesis, we test if they are different, that is:

$H_1: p_g \neq p_k$

<h3>What is the decision rule?</h3>

If the p-value is greater than the significance level, we do not reject the null hypothesis.

If the p-value is less than the significance level, we reject the null hypothesis.

In this problem, the significance level is of 0.1, while the p-value is of 0.6, hence the correct decision for the test is to not reject the null hypothesis.
