## Case Example: Ratio of Males to Females

## Suppose that a survey claimed that more than 60 percent of the graduate student population of the UC system was male. Believing the female population to be larger than they suggest, you conduct a sample survey and found that your sample population of 320 grads consisted of 181 males, a proportion of 56.6%. Are your findings significant enough to suggest a population ratio less than or equal to 60%? Here's the information needed to conduct a hypothesis test.

## = .566

p= .6

q= .4

n= 320
