Question 3 Background: Which t-test? Which t test? For each scenario below determine which type of hypothesis test (one-sample t test for a population mean, paired-samples t test for the population mean difference, or independent-samples t test for the difference in two population means) should be used to assess each of the following alternative hypotheses. Question 3 Subquestions 3.a On average, wives have more years of education than their corresponding husbands 1 pointís) one-sample t test for a population mean paired-samples t test for the population mean difference independent-samples t test for the difference in two population means 3.b 1 point(s) The average number of years of education for wives is 13.4 years one-sample t test for a population mean paired-samples t test for the population mean difference independent-samples t test for the difference in two population means

Explanation / Answer

ANSWER :-

3.a

Option b :- paired samples t test for the population mean difference

Explanation :-

we have to do a paired sample t test as the wives are to be selected to their corresponding husbands

3.b

Option a :- one sample mean test for a population mean

Explanation :-

we have to do a one sample t test for a population mean as there is only one set of obs

3.c

Option c :- independent samples t test for the difference in two population means

Explanation :-

we have to compare average age of persons 1970 and 2000 hence they are independent of each other so we do independent sample t test for population mean
