Answer:
II and III
Step-by-step explanation:
From statement II in the question, it is true that the standard deviations of two different samples from the same population may be the same. The population standard deviation is a fixed value calculated from every individual in the population. A sample standard deviation is calculated from only some of the individuals in a population.
