josie threw a handful of identically shaped buttons into the air , then collected the 27 buttons that landed in the target on the floor, is this a random sample of buttons? yes or no

Answer 1

No, the 27 buttons that Josie collected from the target on the floor are not a random sample of the buttons that were thrown into the air. A random sample should be collected in a way that each individual item has an equal chance of being selected. In this case, only the buttons that landed in the target were collected, which introduces selection bias. Therefore, the sample is not random.
