I'm with Amalia and Troy on this one. The One-Sample t-Test is the perfect fit. Though I must say, the F-Test and Test for Equal Variance seem a bit overkill for this simple question. Maybe the exam writers were just trying to throw us off the scent!

Yeah, it seems like the most appropriate test to validate if they met their requirements.

I agree, the One-Sample t-Test is the way to go for this scenario.

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.

Yeah, the Chi-Square test wouldn't be the right fit for this scenario. The One-Sample t-Test makes more sense here.

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.
