We're going to reject our null hypothesis, which would suggest our alternative. So the key to this question is just to compare this p-value right over here to our significance level. And as we see, the p-value, 0.038, is indeed less than 0.05. And so because of this, we would reject the null hypothesis. We would reject the null hypothesis, which would suggest the alternative, that the true mean is something different than 530 mL. And so if we look at our choices here, so the first choice says reject the null hypothesis. This is strong evidence that the mean filling amount is different than 530 mL.
