1. Compute a .95 confidence for the trimmed mean if (a) n = 24, Sw2= 12, X‾t = 52, (b) n = 36, Sw2= 30, X‾t = 10, (c) n = 12, Sw2= 9, X‾t = 16.
2. Repeat given Exercise, but compute a .99 confidence interval instead.
Exercise
Compute a .95 confidence for the trimmed mean if (a) n = 24, Sw2= 12, X‾t = 52, (b) n = 36, Sw2= 30, X‾t = 10, (c) n = 12, Sw2= 9, X‾t = 16.
