1) Original: How many books does Sandra have?
Statistical investigative version: Among students like Sandra (for example, students in her grade or school), what is the distribution of the number of books owned, and how does Sandra’s number compare to that distribution (mean, median, range, percentiles)?
(Data to collect: number of books owned from a sample or all students in the chosen population; analyses: summary statistics and Sandra’s percentile or z-score.)

2) Original: How many seventh graders eat breakfast on Monday at school?
Statistical investigative version: On a typical Monday, what proportion of seventh graders eat breakfast at school, and how does that proportion vary across different Mondays or subgroups (e.g., by homeroom or gender)?
(Data to collect: whether each seventh grader eats breakfast on several Mondays or a random sample of students on a given Monday; analyses: estimate of the proportion with confidence interval, and comparison of proportions across times/groups.)
