Answer:

A) A larger variance within the population requires a bigger sample size.

Explanation:

The variability of the sample mean is inversely related to the size of the sample; consequently, as the sample size increases, variability declines. Increasing the sample size minimizes the range, thus reducing variance and leading to more precise results with fewer errors in experimentation.

Therefore, using a larger sample size is advised to decrease population variation.

The answer to this open question is as follows.

The devastation resulting from Hurricane Mitch in 1998 included the following.

This catastrophic hurricane resulted in the loss of over 11,000 lives in Central America. It made landfall in this area on October 26 as a category 5 storm, inflicting extensive damage. Experts have deemed Hurricane Mitch as one of the most lethal hurricanes in recent history due to its destruction and the number of fatalities.

In response to this calamity, people in Latin America promptly organized humanitarian assistance once conditions permitted aircraft to reach the region. Aid came in the form of food and supplies, and Latin American nations deployed troops to assist those impacted.

Other frequent natural disasters faced by residents of Latin America include earthquakes and volcanic eruptions. Many recall the significant earthquakes that occurred in México, Haiti, and Chile.

Answer:

In-group favoritism

Explanation:

In-group favoritism occurs when one group is preferred over another, leading to biased decisions. This behavior does not provide healing to individuals; rather, it can be detrimental to others. According to social identity theory, people cultivate a positive self-image. It relates to heightened self-esteem, which leads to favoritism towards certain groups. While this inclination fosters a sense of belonging and connection within the favored group, it can simultaneously result in harmful and negative outcomes for those outside of it.
