Final answer:
To determine the proportion of energy-related stocks in a random sample of 50 stocks, count the number of energy-related stocks in the sample and divide it by the total number of stocks.
Step-by-step explanation:
The question is asking about the proportion of energy-related stocks in a random sample of 50 stocks.
To determine this proportion, you would need to count the number of energy-related stocks in the sample and divide it by the total number of stocks in the sample.
For example, if there are 10 energy-related stocks in the sample of 50 stocks, the proportion would be 10/50 = 0.2 or 20%.
