# Question

Groups of 600 people are randomly selected. Find the mean and standard deviation for the numbers ofpeople with brown eyes in such groups, then use the range rule of thumb to identify the range of usual values for those with brown eyes. For such a group of 600 randomly selected people, is 200 with brown eyes unusually low or high?

Assume that 40% of the population has brown eyes (based on data from Dr. P. Sorita at Indiana University).

## Answer to relevant Questions

When randomly selecting 600 people, the probability of exactly 239 people with brown eyes is P(239) = 0.0331. Also, P(239 or fewer) = 0.484.
