Nope, it's definitely about comparing means.

Wait, are you sure? I thought it was for medians too.

That's actually false, it's about the mean, not the median.

I’m a bit confused; I thought the t-test could be used for both means and medians depending on the context. But I lean towards false for this question.

I practiced a similar question where we discussed the differences between means and medians in hypothesis testing. I feel like this one is also false.

I’m not entirely sure, but I remember something about using the median with non-parametric tests instead of the t-test.

I think the statement is false because a 1-Sample t-test actually compares the mean, not the median, to a target value.

Wait, I thought a 1-sample t-test was used to compare a sample mean to a hypothesized population mean. I don't recall anything about medians. I'm going to have to review this topic before answering.

Okay, let me think this through. A 1-sample t-test is used to make inferences about a population mean when you have a sample from that population. It's not about the median at all. I'm going to go with B, False.

Hmm, I'm a bit unsure about this. I thought a 1-sample t-test was used to compare a sample mean to a hypothesized population mean, not the median. Let me double-check my notes.

I'm pretty confident about this one. A 1-sample t-test is used to compare the mean of a single distribution to a target value, not the median.

I'm pretty sure this is False. The t-test is for comparing means, not medians. Medians are more for non-parametric tests like the Wilcoxon test.

That's correct. The 1-Sample t-test is used to compare means, not medians.
