(c) (5%) Given the following n = 5 observations of X, give a point estimate of θ: 6.6, 7.7, 6.9, 8.3, 7.5.(Please show the process of calculation)

5. (10%) A test of epidemic disease has the following results: to those patients who have been infected, the correct rate (showing positive) is \( 90\% \); however, to the healthy people, there still exists \( 1\% \) error rate (showing positive). Assume the prevalence rate is \( 0.1\% \) (that is, there are 10 persons really infected in 10000 sample). If a man's test reports positive, what is the probability he really infected?
