Do the data provide convincing evidence that the pediatrician's claim is true? Use the a =0.0) level of significance and the P-value method with the TI-84 Plus calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. LL = 25 H : I > 25 This hypothesis test is a right-tailed test. X 5 Part: 1 / 4 Part 2 of 4 Compute the P-value. Round the answer to at least four decimal places. P-value =
