One-year-old Jude Immanuel Bijoy was among five children shifted from the cardiothoracic intensive care unit (ICU) of MIOT Hospital in Chennai Thursday when the hospital realised it could not manage critically ill patients as flood water had knocked out power and oxygen supply for 48 hours.
Now we have to be very careful. There are two standard deviations listed on the calculator. The symbol Sx stands for sample standard deviation and the symbol stands for population standard deviation. If we assume this was sample data, then our final answer would be.
The variance of a set of data is defined as the square of the standard deviation and is thus given by s 2. When it is necessary to distinguish the standard deviation of a population from the standard deviation of a sample drawn from this population, we often use the symbol s for the latter and s for the former. Thus s 2 and s 2 would represent the sample variance and the population variance respectively.
