(numerator) (denominator) c) Find the A-value of the sample test statistic. (Use 4 decimal places.) c) Based on your answers in parts (a) to (c), will you reject or fall to reject the null hypothesis? O Since the P value is greater than the level of significance at a = 0.05, we do not reject Ho. O Since the P value is less than or equal to the level of significance at a - 0.05, we reject Ha O Since the P value is at a - 0.05, we reject Ho. Since the P value is less than or c niticance at a - 0.05, we do not reject H. (e) Interpret your condusion in the context of the application.
