... 1. (32 points) We want to estimate the mean hourly wage for electricians working in Ingham County. We have a list (available from the State of Michigan) of the 540 licensed electricians with addresses in Ingham Country, and will take a simple random sample from this list. a. Suppose we know the wage ...

Solution
... [a, b]. Assume also that g(v) = v 6= u. Then 0 < |u − v| = |g(u) − g(v)| < λ|u − v| < |u − v|, a contradiction. Thus, u = v and we have proved uniqueness. Convergence holds as follows: |u − xn+1 | = |g(u) − g(xn )| ≤ λ|u − xn |, which, by induction, implies convergence of xn to u according to |u − x ...
