Question #: 46
Topic #: 2

Sally and Sara sell flower pots at their garage sale. Sally motivates Sara mentioning that they will sell a minimum of 15 pots per day if the outside temperature exceeds 60o F. From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots. For the sales accomplished above, what test would validate if they met their requirements?

Normal distribution means t-Test fits perfectly here.

Wait, are we sure about that average? Seems low!

Sounds like they didn't quite meet the target.

I think they should have sold more than 15 pots, right?

One-Sample t-Test is the way to go!

I’m confused about the F Test and the t-Test. I know the F Test is for variances, but I can’t remember if we need it here.

I feel like we practiced a similar question where we had to determine if a sample mean was significantly different from a target value. I think it was a t-Test too.

I'm not entirely sure, but I remember something about using the t-Test when the sample size is small. Does 30 count as small?

I think we might need to use a One-Sample t-Test since we're comparing the sample mean to a specific value, which is 15 pots.

This is a tricky one. I'll need to think carefully about the nature of a public blockchain and how data is stored and managed on it.

I'm a bit confused on this one. I know it has something to do with the web.xml file, but I'm not sure which of these options is the right way to do it. I'll have to think it through step-by-step.

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!

Let's stick with the One-Sample t-Test for this one.

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.
