In a census, what method would most appropriately estimate the percentage of Caucasian right-handed individuals?

To estimate the percentage of Caucasian right-handed individuals, it is necessary to consider the probabilities that represent the characteristics in question. The calculation involves multiplying the proportion of the population that is Caucasian by the proportion of that group that is right-handed.

In option C, the multiplication of 0.6 (60% of the population being Caucasian) and 0.9 (90% of Caucasian individuals being right-handed) reflects a logical approach to the problem. This means that 60% of the total population is Caucasian, and from that group, 90% are right-handed, leading to an accurate estimation of the percentage of the overall population that fits both criteria.

By calculating this product, you get 0.54 or 54%, which provides a clear estimate of the percentage of individuals who are both Caucasian and right-handed. This method follows a standard practice in statistics for estimating combined categories and aligns with how demographic probabilities are handled in census data.

In contrasting options, they may respectively present different probabilities for either the Caucasian population or the right-handed portion, leading to estimations that would not accurately reflect the intersection of these groups as described in the question.
