Question: Let \({{X}_{1}},...,{{X}_{n}}\) be i.i.d observations from a \(N\left( \mu ,{{\sigma }^{2}} \right)\) distribution with known variance \({{\sigma }^{2}}\).
a) Formulate the likelihood ratio test for testing Ho: µ = 2 vs H1 : µ > 2 (10 points)
b) Write down the equations needed to determine the sample size n and the critical value c such that the size of the test is 0.05 and the probability of type-II error when \(\mu =2.5\) is 0.1.
c) If we took 16 samples and observed \(\bar{X}\) =2.5, and the population standard deviation is 0.5, compute the p-value based on the data for the test in a). Will you reject H0 at level \(\alpha \) =0.05 based on the p-value calculated? (4 points)
