Answer:
A) The greater the variance within the population, the larger the sample should be.
Explanation:
The variance of a sample mean is inversely proportional to the sample size, that is, the larger the sample size the smaller the variability of the sample. When sample size increases, the range decreases and hence the variance decreases resulting in a more accurate research result with minimal experimental error.
Hence the researcher should employ a large sample size to reduce the variation in the population.

Answer:
An evolutionary theorist would be interested in whether:
c. math abilities are biologically built into being male.
Explanation:
An evolutionary theorist would be concerned with how genes manifest after being passed on from generation to generation. Evolution itself can be defined as the change in characteristics we inherit over time. Since, in the case described, the boy gets good grades in math while the girl doe not, an evolutionary theorist would consider the possibility of a genetic difference between the two being the cause for such an ability. Perhaps, the boy has genes that make it easier for him to learn math.
