Haha, the Chi-Square test? Really? That's for testing the goodness of fit, not for comparing a sample mean to a hypothesized value. Clearly the One-Sample t-Test is the way to go.

I believe we should use the One-Sample t-Test.

Definitely going with the One-Sample t-Test. The question gives us a sample mean and standard deviation, and we need to compare that to a hypothesized value. Classic t-Test scenario.

The One-Sample t-Test seems like the obvious choice here. We want to see if the mean sales of 13.6 pots per day is significantly different from the minimum requirement of 15 pots.
