A medical researcher is investigating the average recovery time for patients after a new surgical procedure. Based on a study of 45 randomly chosen patients, the mean recovery time was estimated to be 18.2 days, with an associated margin of error of 0.8 days. Which of the following statements best describes the plausible range for the true mean recovery time for all patients undergoing this procedure?
The true mean recovery time is likely to be less than 17.4 days.
The true mean recovery time is likely to be greater than 19.0 days.
The true mean recovery time is likely to be between 17.4 days and 19.0 days.
The true mean recovery time is exactly 18.2 days.
