In randomized, double-blind clinical trials of a new vaccine, monkeys were randomly divided into two groups. Subjects in group 1
Mama L [17]

The correct answer is B.

<u>Therefore the appropiate null and alternative hypothesis are the following:</u>

. H 0 : p 1 = p 2

H 1 : p 1 ≠ p 2

The aim of the test would be to conclude whether H0 should be rejected or not at a 10% significance level.

<u>In this case a billateral significance test needs to be conducted,</u> as such a test consists on testing the equality of the test value with a given value. In this case the H0 would be rejected if the test value is significanly different, both in the case that it is superior or inferior.

On the contrary, an unilateral significance test would have been conducted if  aiming to check whether a value is superior or equal to the test value (left unilateral) or inferior or equal to this value (right unilateral).

Then, the result of the test is the one stated: rejecting H0 at the 10% significance level.

You have probably seen pictures of the diverse communities flourishing in the dark depths around hydrothermal vents on the ocean
Galina-37 [17]

Answer: c. Producers.

Explanation:

A hydrothermal source is a crack in the earth through which water flows, was heated under the surface by magma. Heat causes water to flow precipitously to the surface. If the crack is on the earth, it is called Geyser, and if it is underwater, it is called fumarole.

Producers are those organisms that synthesize organic matter from inorganic matter, in marine ecosystems marine plants are the primary producers.

For producers to acquire energy, sunlight is necessary, so it was considered impossible for producers to exist in deep waters in the oceans. However, around the fumaroles ecosystems have been found that subsist only with minerals that come from the expelled water, such as sulfur.

I hope this information can help you.
