We see it up here. They decided to take a sample of 30 medium drinks to see if the average amount, they're not talking about proportions here, they're talking about averages, and in this case, we're talking about estimating the population parameter, the population mean for how much drink is dispensed on that setting. And so this one is looking like this right over here. Only these two are even dealing with the mean. And the difference between this one and this one is this says the mean is greater than 530 milliliters, and that indeed is the owner's fear. And this over here, this alternative hypothesis is that it's dispensing, on average, less than 530 milliliters, but that's not what the owner is afraid of, and so that's not the kind of the news that we're trying to find some evidence for. So I would definitely pick choice C. Let's do another example.
