If we are looking for the proportion of the population that scored between two raw scores, we would first have to
A) translate the raw scores into proportions.
B) look for the proportion in column D of the normal distribution table.
C) convert both raw scores into z-scores.
D) look up the proportion associated with both raw scores in column D and add them together.

To find the proportion of the population that scored between two raw scores, we need to convert both raw scores into their corresponding z-scores using the formula z = (x - μ) / σ. Then, we can use the z-table to find the proportion of scores between those two z-scores. This is because the normal distribution is standardized with a mean of 0 and a standard deviation of 1, so we can use the z-scores to find the proportion of scores in that range.
