3) Explain what is meant by constructing a confidence interval for an unknown parameter 0 from a given sample x1, ..., x. Let a family of PDFS S(x; 0). -0 < 0 0, 0. x< 0. S(x; 0) = Suppose that n = 4 and x, = -1.0, x, = 1.5, x, = (0.5, x, = 1.0. Construct a 95% confidence interval for 0. (ii) Let f(x: u, o²) be a family of normal PDFS with an unknown mean u and an unknown variance o'> 0. Explain how to construct a 95% confidence interval for a from a sample x,, . x. Justify the claims about the distributions you use in your construction.

3) Explain what is meant by constructing a confidence interval for an unknown parameter 0 from a given sample x, ..., N. Let a family of PDFS fS(x: 0). -o < 0<o, be given by e-(i-), x> 0, S(x: 0) = 0. x< 0. Suppose that n = 4 and x, = -1.0, x, = 1.5, x, = (0.5, x, = 1.0. Construct a 95% confidence interval for 0. (ii) Let f(x: p, o²) be a family of normal PDFS with an unknown mean u and an unknown variance o² > 0. Explain how to construct a 95% confidence interval for a from a sample x, . , x. Justify the claims about the distributions you use in your construction.
