To decide what personnel requirements should be enforced, a hospital manager wants to estimate the mean number of people who are admitted to the emergency room during a 24-hour period. The director randomly selects 48 different 24-hour periods and counts the number of admissions for each. In his sample, the sample mean is 296 and the sample standard deviation is 89. Estimate the mean number of admissions per 24-hour period with a 95% confidence interval
