Question

maridel wants to find out how many of her classmates plan to come to the next football game. there are 800 students in her school. she selects a sample of the population by putting the names of every student into a bag and drawing out 100 names. which statement(s) describe her sampling method? check all that apply. her method will produce a biased sample. her method will produce a valid sample. her method will produce a random sample. her method will produce a representative sample. her method will produce an invalid sample.

Explanation:

Maridel is using simple - random sampling as she is randomly selecting 100 names out of 800 by drawing from a bag. A simple - random sample is likely to be valid and representative if the sample size is appropriate relative to the population size. Since there is no reason to believe there is any bias in the selection process (every student has an equal chance of being selected), it is not a biased or invalid sample.

Answer:

Her method will produce a valid sample.
Her method will produce a random sample.
Her method will produce a representative sample.
