6.42) Percentiles and eating habits: As noted in How it works 6.1, Georgiou and colleagues (1997) reported that college students had healthier eating habits, on average, than did those individuals who were neither college students nor college graduates. The 412 students in the study ate breakfast a mean of 4.1 times per week, with a standard deviation of 2.4 (for this exercise, again imagine that this is the entire population of interest)

1. What is the approximate percentile for a student who eats breakfast four times per week?
2. What is the approximate percentile for a student who eats breakfast six times per week?
3. What is the approximate percentile for a student who eats breakfast twice a week?
