Can Some one help me on this question?
A medical researcher wants to show that a muscle relaxant produces drowsiness in a smaller proportion of patients suffering from a particular disorder than the 40% in which this occurs under the standard treatment. Set up the appropriate hypotheses for training for gaining this evidence. If 70 of 200 patients tested reported drowsiness, do you feel that the claim was substantiated? Justify your answer on the basis of the P value of the test.
