What are the degrees of freedom? (c) Find or estimate the P-value of the sample test statistic. O p-value > 0.100 O 0.050 < p-value < 0.100 O 0.025 < p-value < 0.050 O 0.010 < p-value < 0.025 O 0.005 < p-value < 0.010 Op-value < 0.005 (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null O Since the P-value > a, we fail to reject the null hypothesis. O Since the P-value > a, we reject the null hypothesis. O Since the P-value < a, we reject the null hypothesis. O Since the P-value s a, we fail to reject the null hypothesis.
