Final answer:
The question asks to estimate the population proportion of students who prefer a particular meal but does not provide sufficient data to calculate the proportion. We need the number of students who prefer the Chinese combo plate and the total number of students surveyed. Without this, we cannot select the correct answer.
Step-by-step explanation:
The question regarding Ventana high school's estimation of the population proportion of students who prefer the Chinese combo plate is a typical statistics problem. To answer the question, you would need additional data such as a sample proportion or number of students surveyed who prefer the Chinese combo plate. Without this information, we cannot deductively select the correct answer from the choices provided (a) 0.25, (b) 0.50, (c) 0.75, or (d) 0.90.
If Ventana High School provided data indicating that, for example, 250 out of 1000 students preferred the Chinese combo plate, we could then use that sample to estimate the population proportion. The calculation would be 250/1000, which is 0.25, and answer choice (a) would be correct. However, without such data, we cannot make an accurate estimation.
Understanding how to calculate proportions and percentages is important in statistics. When working with population proportions, one common approach is to take a sample and use the results to estimate the parameter for the entire population. This is often accompanied by a confidence interval, which gives an estimate of the range in which we believe the true proportion lies.
