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.
So what people like to do is talk in terms of standard deviation, which is just the square root of the variance, or the square root of sigma squared. And the symbol for the standard deviation is just sigma. So now that we've figured out the variance, it's very easy to figure out the standard deviation of both of these characters. The standard deviation of this first one up here, of this first data set, is going to be the square root of 200.
