The statement '27.2% of the mayors of cities in a certain state are from minority groups' is a statistic, not a parameter.
Step-by-step explanation:
In this context, the statement '27.2% of the mayors of cities in a certain state are from minority groups' is a statistic. A statistic is a numerical value calculated from a sample of data and used to describe a characteristic of a population. In this case, the percentage of mayors from minority groups is the statistic that represents the proportion of minority mayors in the sample of cities in the state.
It is important to note that a parameter is a numerical value that describes a characteristic of a population as a whole. Since we are dealing with a sample of mayors in cities, rather than the entire population of mayors in the state, the statement represents a statistic rather than a parameter.
