V. Hypothesis test and confidence intervals. 1. A sample (n) is taken at random from a population and produces (the sample) A = 1100, S = 200. Try the following hypothesis: If we assume the following size of sample n = 36 a, Is there evidence that the average μx is less than 1200? α = .10 H0: μx = 1200 H1: μx <1200 * For the previous test (item a) estimate the p-value * Determine the power of the...
