A school administrator is curious what proportion of the 2,400 students at the school regularly eat breakfast. They take an SRS of 150 of these students, and 104 of them report that they regularly eat breakfast. The administrator wants to use this data to construct a one-sample z interval for a proportion. Which conditions for constructing this confidence interval did their sample meet? Choose all answers that apply: The data is a random sample from the population of interest. The observed counts of successes and failures are both sufficiently large. Individual observations can be considered independent.
