Question

The graph contains 10 sampling proportions; the data is based on a survey asking people what type of phones they own. Based on the graph, is it possible to determine the percentage of people who own a specific brand of phone? (1 point) Responses Yes, it is possible because even though the graph is not symmetrical, you can still make use of the 10 sample proportions to make an estimate of the population proportion. Yes, it is possible because even though the graph is not symmetrical, you can still make use of the 10 sample proportions to make an estimate of the population proportion. Yes, it is possible because the sampling distribution is symmetric. Yes, it is possible because the sampling distribution is symmetric. No, because there is less variability in samples of small sizes. No, because there is less variability in samples of small sizes. No, the data number is so small that the variability will be high; it is not possible to make an approximation of the population proportion.

Answer 1

Based on the information provided in your question, the best response would be:

No, the data number is so small that the variability will be high; it is not possible to make an approximation of the population proportion.

While you can use sample proportions to estimate the population proportion, a small sample size can lead to higher variability in the estimates. This means that the results might not accurately reflect the true population proportion, making it difficult to draw reliable conclusions. Thus, the small number of samples may not provide a robust estimate of the population proportion.
