•The purpose of a study by Luglie was to investigate the oral status of a group of patients diagnosed with thalassemia major (TM) . One of the outcome measure s was the decayed , missing, filled teeth index (DMFT) . In a sample of 18 patients ,the mean DMFT index value was 10.3 with standard deviation of 7.3 . Is this sufficient evidence to allow us to conclude that the mean DMFT index is greater than 9 in a population of similar subjects? Let α =0.05

Question 71

a simple binary communication channel carries messages by using only two signals; say 0 and 1. We assume that; for a given binary channel, 40% of the time a 1 is transmitted; the probability that a transmitted 0 is correctly received is 0.90,and the probability that a transmitted 1 is correctly received is 0.95. given 1 is received, probability that 1 was transmitted
