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:
rehearsal
Explanation:
Hello! To keep the numbers in memory, Randy does rehearsal until he could write the new information down. The information is retained for a short time until such information is processed or can be recorded, this is achieved by repeating (and retaining) the numbers in the mind.

I believe the correct answer is the first option - <span>Implementing a solution involves putting a plan into action based on several factors.
First, you will weigh your options and decide on which path to go. Then you will take that one particular option and implement it in order to get the results you wanted. Implementation occurs after you've decided what the best option is so it is the penultimate step.
