The proportion of people who relapse at twelve months posttreatment for heroin addiction is 0.75. Suppose that researchers at a treatment facility use simple random samples to ensure that this number is not changing. Determine the value of ?̂ p^such that in 99% of all simple random samples of size ?=50, the proportion of people in the sample who relapse at twelve months posttreatment for heroin addiction is less than ?̂ .than p^. You make find a ?-tablez-table or some software manuals useful. Please give your answer to two decimal places.
