Question

Quizplus · Accepted Answer

A t-test for a single sample is used to compare the mean of a single sample to a known value or theoretical expectation (in this case, the hours that "C" average students spend on Facebook each week compared to an expected value, such as the average for students in general). Choices A, B, and C involve comparing two different groups or the same group at two different times, which would require different types of t-tests or statistical analyses.
