A random sample of blood test results from inmates was taken from a state department of corrections. The probability that a male inmate was positive for the hepatitis C virus (HCV) is 36%. The probability that a male inmate was HCV positive and reported that they used IV drugs is 29%. What is the probability of randomly choosing one inmate who used IV drugs given that they are HCV positive?

Try the following hypothesis: If we assume the following size of sample n = 36 a, Is there evidence that the average μx is less than 1200? α = .10 H0: μx = 1200 H1: μx <1200 * For the previous test (item a) estimate the p-value * Determine the power of the...
