Solution
The question seems to be asking for the standard deviation of the marks scored by students in two sections of a class. However, the data provided is not sufficient to calculate the standard deviation directly.
The standard deviation is a measure of the amount of variation or dispersion in a set of values. A low standard deviation means that the values tend to be close to the mean (average) value of the set, while a high standard deviation means that the values are spread out over a wider range.
To calculate the standard deviation, you would first need to calculate the mean of the set of values. Then, for each value in the set, you would subtract the mean and square the result. The next step is to calculate the mean of these squared differences. Finally, you take the square root of this last mean.
In Excel, you can use the STDEV.S function to calculate the standard deviation of a sample. In Google Sheets, you can use the STDEVA function.
Without doing the calculations, it's not possible to determine which of the provided options is correct.
