The Human Resources Director of a central hospital wishes to estimate the mean number of children admitted to the pediatric clinic during a day. The director randomly selects 41 different days and determines the number of admissions for each. Based on this sample, she computes X-bar = 19.8 and S2 = 25. You are requested to estimate the mean number of admissions per day with a 95% confidence interval. A. 18.11 ≤ μ ≤ 21.49 B. 18.49 ≤ μ ≤ 21.11 C. 18.63 ≤ μ ≤ 20.97 D. 18.26 ≤ μ ≤ 21.34 E. 18.22 ≤ μ ≤ 21.38
