Length of hospital stays A hospital administrator wants to estimate the mean length of stay for all inpatients using that hospital. Using a random sample of 100 records of patients for the previous year, she reports that “The sample mean was 5.3. In repeated random samples of this size, the sample mean could be expected to fall within 1.0 of the true mean about 95% of the time.” Explain the meaning of this sentence from the report, showing what it suggests about the 95% confidence interval.
