Question

in a study of a sample of babies born at hospitals in one state, it was found that the average (mean) weight at birth was 3168.6 grams. identify whether this value is a statistic or a parameter. choose the correct answer below. a. the value is a parameter because it describes some characteristic of a sample. b. the value is a statistic because it describes some characteristic of a sample. c. the value is a statistic because it describes some characteristic of a population. d. the value is a parameter because it describes some characteristic of a population.

Explanation:

A statistic is a characteristic of a sample, while a parameter is a characteristic of a population. Here, the average weight is calculated from a sample of babies born at hospitals in one state. So it's a statistic as it describes a characteristic of the sample.

Answer:

B. The value is a statistic because it describes some characteristic of a sample.
