Question

Are blonde female college students less likely to have boyfriends than brunette female college students? 446 of the 639 blondes surveyed had boyfriends and 512 of the 720 brunettes surveyed had boyfriends. What can be concluded at the αα = 0.10 level of significance?

The p-value is αα
Based on this, we should the null hypothesis.
Thus, the final conclusion is that ...
- The results are statistically insignificant at αα = 0.10, so we can conclude that the population proportion of blonde college students who have a boyfriend is equal to the population proportion of brunette college students who have a boyfriend.
- The results are statistically significant at αα = 0.10, so there is sufficient evidence to conclude that the proportion of the 639 blonde college students who have a boyfriend is less than the proportion of the 720 brunette college students who have a boyfriend.
- The results are statistically significant at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of blonde college students who have a boyfriend is less than the population proportion of brunette college students who have a boyfriend.
- The results are statistically insignificant at αα = 0.10, so there is insufficient evidence to conclude that the population proportion of blonde college students who have a boyfriend is less than the population proportion of brunette college students who have a boyfriend.
