Suppose that a company knows that its monthly average net profits tend to be normally distriubuted, but knows neither the mean nor the standard deviation of this distribution. Suppose that the company wants to test the hypothesis we to whether the mean of the distribution of these profits is 25, or . What can be said about this hypothesis, given that the company has collected the following data:
