Computing a con?dence interval

Reference no: EM13965197

(a) Suppose we construct a 99% con?dence interval. What are we 99% con?dent about?

(b) Which of the con?dence intervals is wider, 90% or 99%?

(c) In computing a con?dence interval, when do you use the t-distribution and when do you use z, with normal approximation?

(d) How does the sample size affect the width of a con?dence interval?

2. Suppose X is a random sample of size n = 1 from a uniform distribution de?ned on the interval (0, θ). Construct a 98% con?dence interval for θ and interpret.
