A new drug is designed to reduce a personʹs blood pressure. Thirteen randomly selected
hypertensive patients receive the new drug. Suppose the probability that a hypertensive
patientʹs blood pressure drops if he or she is untreated is 0.5. Then what is the probability
of observing 11 or more blood pressure drops in a random sample of 13 treated patients if
the new drug is in fact ineffective in reducing blood pressure? Round to six decimal
places.
