Answer:

Lighting significantly affects performance

Explanation:

In this study, Ellen took two groups and applied the same IQ test to both of them. The only variable that changed between the groups was the level of lighting in the room. The first group was placed in a room with very bright lights and the second group was placed in a room with more normal lighting.

Individuals in the first group did better in the IQ test and she found that the difference between the two scores was statistically significant.

We say that a result is <u>"statistically significant" when it is not likely to occur randomly but rather is likely to be attributable to a specific cause.</u>

<u />

So we can say that <u>the better performance in the first group tests were not likely to occur randomly but it can be attributable to a specific cause. </u>

<u></u>

<u>Since the only variable that was different between the groups was the lightning, we can conclude that lighting significantly affects performance. </u>

Answer:

On September 27, 1940, Japan signed the Tripartite Pact with Germany and Italy, thus entering the military alliance known as the "Axis." Seeking to curb Japanese aggression and force a withdrawal of Japanese forces from Manchuria and China, the United States imposed economic sanctions on Japan. Faced with severe shortages of oil and other natural resources and driven by the ambition to displace the United States as the dominant Pacific power, Japan decided to attack the United States and British forces in Asia and seize the resources of Southeast Asia. Japan launched a surprise attack on the United States Pacific fleet at Pearl Harbor, Hawaii, on December 7, 1941. The attack severely damaged the American fleet and prevented, at least for the short term, serious American interference with Japanese military operations. In response, the United States declared war on Japan. Following Germany's declaration of war on the United States, the United States also declared war on Germany..
