To develop a confidence interval estimate of the population mean rating for Miami International Airport, we need to use the ratings obtained from the sample of business travelers. Unfortunately, the specific ratings from the sample are not provided in the user’s message. However, we can still discuss the general process of calculating a confidence interval for the population mean rating.

Here is a general outline of the steps involved in calculating a confidence interval for the population mean rating:

  1. Collect the sample ratings: Obtain a simple random sample of business travelers and record their ratings for Miami International Airport.

  2. Calculate the sample mean: Find the average rating of the sample.

  3. Calculate the sample standard deviation: Determine the standard deviation of the sample ratings.

  4. Determine the sample size: Note the number of ratings in the sample.

  5. Choose a confidence level: Decide on the desired level of confidence for the interval estimate. For example, a 95% confidence level is commonly used.

  6. Calculate the margin of error: Determine the margin of error using the appropriate formula based on the sample size, sample standard deviation, and chosen confidence level.

  7. Calculate the confidence interval: Use the sample mean, margin of error, and confidence level to calculate the confidence interval estimate of the population mean rating.

Without the specific ratings from the sample, we cannot provide the exact confidence interval estimate for the population mean rating of Miami International Airport. However, by following the steps outlined above and using the provided sample ratings, you can calculate the confidence interval estimate.
