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 population standard deviation is calculated using =STDEV(VALUES) and in this case the command is =STDEV(A2:A6) which produces an answer of 0.55. The sample standard deviation will always be greater than the population standard deviation when they are calculated for the same dataset. This is because the formula for the sample standard deviation has to take into account the possibility of there being more variation in the true population than has been measured in the sample. Based on their sample of 5 cars, and therefore using the sample standard deviation, the manufacturers could state with 99% confidence that similar cars will do between 14.57 (MEAN-3SD) and 17.87 (MEAN+3SD) kilometres per litre .
