The weight, in grams, of 10 bags of sweets are as follows:
251, 253, 254, 249, 249, 248, 250, 251, 252, 247
If it is assumed that the weights of the 10 bags of sweets in the preceding questions represent the entire population of weights in which we are interested, what is the standard deviation of these weights?
any idea how to work out the standard deviation?
- 2.11g
- 4.45g
- 4.93g
- 2.22g
- None of the above.
