(\"I point) A random sample of n measurements was selected from a population with unknown mean ,9. and standard deviation 0'. Calculate a 99% condence interval for p: for each of the following situations: (a) n = 12, E = 94.7, s = 3.85 EMS (b) 11:28, E277, 5:2.32 (o) n = 12, E = 65.3, s = 4.22 EMS (d) n=21,E=3,5=3.4Q EMS
