For AP Stats my study sheet has the following question: When the sample is small why is it necessary to inspect a graph of the sample data when calculating a confidence interval for a population mean?

I think it is to: "verify that the population can be considered approximately normal" Am I right?

other options listed:

to verify that the central limit theorem is right

so we can use a critical value instead of a t value

so that the statistic is an unbiased estimator

so that the formula for the standard error is approximately correct
