Question
Based on a simple random sample, is there a difference in the proportion of married people between the education levels of Less than High School and More than High School?
To answer this statistical question, which statistical procedure should be/should not be used and why?
Respond and explain why. (The typical format for each answer is "yes/no, [reason why each works or does not work]")
The hypothesis test to compare two proportions? Explain Chi-Square Test of Independence? Explain. Hypothesis test to compare two independent means? Explain. Hypothesis test for Paired Comparisons? Explain. ANOVA? Explain.
Solution
-
The hypothesis test to compare two proportions? Yes, this is the appropriate statistical procedure to use. The question is asking about the difference in proportions (i.e., the proportion of married people) between two groups (i.e., those with less than a high school education and those with more than a high school education). A hypothesis test for two proportions can determine if there is a significant difference between these two proportions.
-
Chi-Square Test of Independence? Yes, this could also be used. The Chi-Square Test of Independence tests whether two categorical variables are related. In this case, the two variables are education level and marital status. If the p-value is less than the chosen significance level, we would reject the null hypothesis that the variables are independent, suggesting a difference in the proportion of married people between the two education levels.
-
Hypothesis test to compare two independent means? No, this would not be appropriate. This test is used when comparing the means of two independent groups, not proportions. In this case, we are interested in proportions (i.e., the proportion of married people), not means.
-
Hypothesis test for Paired Comparisons? No, this would not be appropriate. This test is used when the same individuals are measured twice under different conditions or when individuals are paired in some meaningful way. In this case, the two groups (those with less than a high school education and those with more than a high school education) are independent, not paired.
-
ANOVA? No, this would not be appropriate. ANOVA is used to compare the means of three or more groups. In this case, we are only comparing two groups and we are interested in proportions, not means.

A large university took a random sample of the students and found that 35% were married. The researcher wondered if that proportion was the same for the entire student population. When the marriage records of all students were checked, the researcher found out that 31% of the students were married. Which of the following is the correct statement?Group of answer choicesBoth 35% and 31% are statisticsThe 35% is a statistic and 31% is the parameterBoth 35% and 31% are parametersThe 31% is a statistic and the 35% is the parameter
