Answer:YES , It would be appropriate for her to analyze her data using an independent samples t-test

Explanation:

The independent samples t-test is used to make comparisons between two independent groups so that it can be established that there is a major difference between these two groups statistically .

It can not be used to compare more than two groups. The participants of each group will stick to their original group without interfering with the other group.

They are also assigned to each group randomly in no particular considerations.

Kimberly' s path to determining her hypothesis fit well with this test , she desires to measure the significant difference between the means of both groups and she selected and assigned them randomly

Why do the seasons happen?
juin [17]

Answer:As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.

In other words: Earth has seasons because its axis is tilted. Earth's axis is always pointed in the same direction, so different parts of Earth get the Sun's direct rays throughout the year. ... Many people believe that Earth is closest to the Sun in summer and farthest in winter...

If you don't understand those ways here's one you may understand: The reason we have seasons is because, during its journey around the Sun, the Earth is tilted. The Earth's tilt affects the amount of daylight each hemisphere gets, which in turn makes the temperature hotter or colder.

Those are some ways we have seasons...

By the way, what's your favorite season???

Hope this helps.. Stay safe and have a great day/night!!! :D

Sophie [7]

Answer:

Explicación:

Se interpreta esta frase como un saludo de advertencia a la monarquia que apoyaba al sistema y un rechazo total al gobierno. considerando no al jefe de estado si no a todos los colaboradores del mismo como ministros los cuales formaban el aparato burocratico.

Por otra parte al estar las jefaturas de estado divididas por las malas politicas y erradas el rey no corre ningun peligro porque no se le atribuye esta mala gestion.
