The question is following:

An investor is considering contributing money to help open a restaurant (e.g., Netflix's Million Pound Menu). Apparently, an important part of investing is estimating how much revenue a restaurant is making. A savvy investor knows from previous experience that the reliability of revenue scores is .75, the average revenue for these kinds of restaurants is 24,000 CAD, and the standard deviation of revenue is 5,000 CAD. The current investment opportunity is observed to have a revenue of 50,000 CAD. The ever-cautious investor wants to a range of what the true revenue is likely to be with 95% confidence.

What level of measurement is revenue? (3-points)

Calculate the investors best guess at the true revenue point estimate. (5-points)

Calculate a 95% confidence interval (5-points)

Interpret that confidence interval in relatively plain English using the context of this problem. (5-points)
