Question

Quizplus · Accepted Answer

A one-sample t test is appropriate for testing a hypothesis about the population mean of a single group. In this case, the hypothesis is about the average GPA of all students after one semester, which is a single population parameter. Option A involves comparing the means of two independent groups (men and women) and requires a two-sample t test. Option B suggests a correlation between two variables and requires a correlation analysis. Option D involves testing the interaction between two independent variables (hours spent studying and gender) and requires an ANOVA with interaction effects.
