According to the Central Limit Theorem. The mean of a sampling distribution will equal the [pop_mean]. The standard deviation of a sampling distribution will equal [sigma]. The sampling distribution approaches a [symmetrical] shape as [N] increases.

Exam 2, which covers chapters 6, 7, 8 and 9, is due on Tuesday, 4/7. Two attempts are available for this exam. However, you get only 80% from your second attempt. The highest of first attempt and 80% of second attempt will be recorded in this exam. So, if you receive 80 points or above in first attempt, there is no need to take second attempt. You need to take this exam through Honorlock.

While racial categories have profound social and cultural realities, scientific evidence states that there is no biological basis for how we classify racial groups. Explain this conclusion by addressing both phenotypic and genotypic variation in humans: Part A: Explain why phenotypic traits associated with race, such as skin color, are impossible to categorize into discrete groups. What is the term for these traits, and why does it matter with regard to their variation? Part B: Describe the global patterns of human genetic diversity. Specifically, how does the amount of genetic variation within a traditionally defined racial group compare to the variation between different groups, and what does this mean for biological classification?
