Question

For this study, we should use Select an answer z-test for the difference between two population proportions t-test for the difference between two independent population means t-test for the difference between two dependent population means z-test for a population proportion t-test for a population mean

The null and alternative hypotheses would be:

H0:H0: Select an answer μ1 p1 Select an answer > ≠ < = Select an answer μ2 p2 (please enter a decimal)

H1:H1: Select an answer μ1 p1 Select an answer ≠ = < > Select an answer μ2 p2 (Please enter a decimal)

The test statistic ? t z = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? > ≤ αα
Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
Thus, the final conclusion is that ...
- The results are statistically insignificant at αα = 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.
- The results are statistically insignificant at αα = 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.
- The results are statistically significant at αα = 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.
- The results are statistically significant at αα = 0.05, so there is sufficient evidence to conclude that the proportion of the 663 blonde college students who have a boyfriend is greater than the proportion of the 763 brunette college students who have a boyfriend.
Interpret the p-value in the context of the study.
- There is a 23.88% chance of a Type I error.
- There is a 23.88% chance that blonde college students are 1.8% more likely than brunette college students to have a boyfriend.
- If the percent of all blonde college students who have a boyfriend is the same as the percent of all brunette college students who have a boyfriend and if another 663 blonde college students and 763 brunette college students are surveyed then there would be a 23.88% chance that the percent of the surveyed blonde college students who have a boyfriend would be at least 1.8% more than the percent of the surveyed brunette college students who have a boyfriend.
- If 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 663 blonde college students and 763 brunette college students are surveyed then there would be a 23.88% chance of concluding that blonde college students are at least 1.8% more likely than brunette college students to have a boyfriend
Interpret the level of significance in the context of the study.
- If the percent of all blonde college students who have a boyfriend is the same as the percent of all brunette college students who have a boyfriend and if another 663 blonde college students and 763 brunette college students are surveyed then there would be a 5% chance that we would end up falsely concuding 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
