Question

In a random sample of 100 paintings at a very large museum, 40 are worth over $100,000. Goal: construct a 95% confidence interval to estimate the proportion of all paintings at the museum that are worth over $100,000 (complete questions a-d).

Question a: What is the statistic (p-hat)?

Question b: What is the confidence coefficient (z*) for a 95% confidence interval?

Question c: What is the 95% confidence MOE?

Question d: What is the 95% confidence interval to estimate the proportion of all paintings at the museum that are worth over $100,000?

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
