The correct answer is option c. an advanced economy, and over the past century its rate of economic growth has been lower than that of the United States.
Explanation:
The United States has the most technologically powerful economy in the world. American companies are at the forefront of technological advances, especially in computers, pharmaceuticals and medical, aerospace and military equipment; However, its advantage has been reduced since the end of World War II. Until 2014, the United States remained the largest in the world for more than a century.
When testing a hypothesis using a null hypothesis, you use a statement that negates your hypothesis, and, within a certain level of certainty, see if the null hypothesis can be rejected. When testing the null hypothesis, you typically want to be around 95% sure that you can reject it (confidence interval is 95%).
In Rose's case, she is testing the hypothesis that there is a correlation between watching violence on television and aggressive behavior.
Her null hypothesis would be:
"There is not a positive correlation between watching violence on television and aggressive behavior"
or
"The correlation between watching violence on television and aggressive behavior is less than or equal to zero"
