The director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period.
The director randomly selects 36 different 24-hour periods and determines the
number of admissions for each.
For this sample, x = 15.8 and s2 = 9
Estimate the mean number of admissions per 24-hour period with a 98% confidence
interval.
O 15.8 + 1.165
O 15.8 + 3.495
O 15.8 + 1.94
O 15.8 + .490
