Final answer:
Based on the inconsistent information provided, which suggests myopia (nearsightedness) affects about 8% or one third of the population, the correct option would be C, 8%. However, one third is significantly greater than 8%, which suggests a discrepancy in the provided data.
Step-by-step explanation:
The question pertains to estimating the probability of the condition of myopia, also known as nearsightedness, in the population. Myopia is a condition where people can see nearby objects clearly but have difficulty seeing distant objects sharply. The reference information states that myopia affects about one third of the population.
When estimating probabilities, one should look for the option that best aligns with the given data or statistical norm. Out of the provided options, the closest estimate to the one-third statistic mentioned is option (c) 8%. This is because one third is approximately equivalent to 33%, and while none of the answer choices are close to 33%, the only reasonable choice considering common estimations of myopia prevalence would be 8%. Therefore, the correct response to the question would be option C, estimating nearsightedness to affect 8% of the population. However, the information provided seems to have an inconsistency as it suggests both 8% and one third, which are significantly different. Usually, nearsightedness affects a larger percentage of the population than 8%. The other options provided (10%, 5%, 15%) are either too high or too low compared to the provided reference that it affects about one third of the population.
