1. 假設線性迴歸式為：Y = β0 + β1X +，β0、β1 是參數，是誤差，樣本大小為 n。依據這個模式回答兩個問題： (1) β_1 的估計滿足一致性(consistency)指的是什麼？(10%)

3. A rare medical condition affects only 1 in 50,000 people in a specific population. A sophisticated diagnostic test for this condition has the following characteristics: If a person has the disease, the test is \(99.5\%\) accurate in detecting it (sensitivity). If a person does not have the disease, the test has a \(1.5\%\) false positive rate. Two independent tests are performed on the same patient. What is the probability (%) that a person actually has the disease, given that they tested positive on the first test and also tested positive on the second test? (20%) (Note: You are asked to answer in percentages, counted to two decimal places.)

1. 假設線性迴歸式為：$Y = \beta0 + \beta1X + \varepsilon$，$\beta0$、$\beta1$ 是參數，$\varepsilon$ 是誤差，樣本大小為 n。
