The independent-samples t test command in SPSS is used to test for a difference between two means when the samples are independent, meaning that the individuals in one sample are not related to the individuals in the other sample. In this case, heavy users and nonusers are distinct groups, so we would use the independent-samples t test command. Choice A is similar but does not specify that the samples are independent, and choice B is incorrect because it refers to "TWO" when we are comparing two groups. Choice C is not appropriate because the paired samples t test is used when the individuals in one sample are related to the individuals in the other sample (e.g., before and after measurements on the same individuals). Choice E is not a valid SPSS command.
