Is there evidence that the population of American females is, on average, getting less than the recommended 15 mg of iron? That is, should we reject the null hypothesis H 0: μ = 15 against the alternative H A: μ < 15? The US National Research Council currently recommends that females between the ages of 11 and 50 intake 15 milligrams of iron daily. For a two-tail test multiply the one-tail probability by two.

The P-value is this probability for a lower-tail test or one minus this probability for an upper-tail test.

The probability that a t-distributed random variable with this number of degrees of freedom is less than or equal to the test statistic will appear in the session window. In the box, type the test statistic for which you want to find the associated cumulative probability.
