A researcher interested in the transition from middle school to high school surveys a random sample of 200 eighth-grade students. Which of the following statistics are computed using binomial data? The average height of the students in the sample The proportion of the sample who plans to attend a private high school The total number of siblings among students in the sample The schools currently attended by students in the sample Suppose that the researcher wants to conduct a hypothesis test about the proportion of her sample who have a pet at home.
