<span>The factors that turned ferns into fossil fuels over thousand of years are pressure and heat.Ferns live in swamp forests, when they died and decayed they formed layers at the bottom of the swamp. Soil and water will built up and the heat and pressure would cause the decayed ferns to change over thousands of years, continuing to decay in the absence of oxygen will turn the fern into fossil fuels. <span>

Is the temperature profile in the thermosphere more like that of the troposphere or the stratosphere?

podryga [215]

The correct answer is: stratosphere.

This is because their temperatures are rising instead of decreasing.

There are 4 primary layers of the atmosphere on Earth:

Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.

Stratosphere (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.

Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer

Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.

A phycologist is interested in testing the claim that the proportion of algae from a local rivulet that belonged to the particul

Shkiper50 [21]

Answer:

The test statistic for this hypothesis test is - 3.68.

Explanation:

A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.

Sample proportion = 38/50

= 0.76

Hence,

Test statistic

$= \frac{0.76-0.50}{\sqrt{0.50*0.50/50}}$
