Based on this data, which of the following conclusions are valid?
Choose 1
A
About 80% of all of Jonas's classmates may tell their dreams.
B)
About 80% of all people in Jonas's community may tell their dreams.
C)80% of the classmates in this sample may tell their dreams, but we cannot
conclude anything about the population.
