T tets is one of the useful tests in the testing of a hypothesis. This test can be used for both dependent samples and independent samples. Using this test we can find the significant difference between the means for a single sample as well as two samples.
Step 2
The t-test is used only for two variables, if there are more than two then we use ANOVA to compare the groups. If one variable is related to another variable then they are correlated or we can say they are dependent. If one variable is not related to another then they are independent.
From the above explanation,
The t-test for dependent means, You are comparing exactly two groups that are related
The required option is,
Option D: You are comparing exactly two groups that are related
Reason to reject other options:
Options A and B rejected because there ate more than two groups are there. using a t-test we can compare only two groups. Hence we reject
Option c is rejected because dependence means they are related to each other. but here it is given unrelated. hence we decline this option.
