A new drug is being tested to see whether it can reduce the chance of heart attack in people who have previously had a heart attack. The rate of heart attack in the population of concern is 0.20. The null hypothesis is that p (the population proportion using the new drug that have a heart attack) is 0.2. Pick the correct alternative hypothesis. 

i. p ≠ 0.2 

ii. p > 0.2 

iii. p < 0.2
