Question
Are blonde female college students more likely to have boyfriends than brunette female college students? 439 of the 658 blondes surveyed had boyfriends and 483 of the 748 brunettes surveyed had boyfriends. What can be concluded at the a = 0.05 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answerv Select an answer Select an answer (please enter a decimal) H1: Select an answer v Select an answerv Select an answerv (Please enter a decimal) b. The test statistic ?v = (please show your answer to 3 decimal places.) c. The p-value = d. The p-value is ?v a e. Based on this, we should Select an answerv the null hypothesis. f. Thus, the final conclusion is that... (Please show your answer to 4 decimal places.) O The results are statistically insignificant at a = 0.05, 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. O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population proportion of blonde college students who have a boyfriend is greater than the population proportion of brunette college students who have a boyfriend. O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the proportion of the 658 blonde college students who have a boyfriend is greater than the proportion of the 748 brunette college students who have a boyfriend. O The results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude that the population proportion of blonde college students who have a boyfriend is greater than the population proportion of brunette college students who have a boyfriend. g. Interpret the p-value in the context of the study. O There is a 19.91% chance of a Type I error. O f the sample proportion of blonde college students who have a boyfriend is the same as the sample proportion of brunette college students who have a boyfriend and if another another 658 blonde college students and 748 brunette college students are surveyed then there would be a 19.91% chance of concluding that blonde college students are at least 2.1% more likely than brunette collese students to have a boyfriend
