Question: Georgiou and colleagues (1997) reported that college students had healthier eating habits, on average, than did those 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, imagine that this is the entire population of interest; thus, these numbers can be treated as parameters.
a. Roughly, what is the percentile for a student who eats breakfast four times per week?
b. Roughly, what is the percentile for a student who eats breakfast six times per week?
c. Roughly, what is the percentile for a student who eats breakfast twice a week?
