Among college-age students (18-24 years old), 9.2% have hypertension. During a blood-donor program conducted during finals week, a blood-pressure reading is taken first, revealing that out of 2000 donors, 220 have hypertension. Part One: The sample proportion of successes (p-hat) is (to four decimal places)    Assuming that hypertension in finals week is the same as at other times, what is the probability of getting a sample result as large as ours (p-value)?    which comes from a test-statistic of z=   (without sign)
