Course: BUS173; Assignment #01 Problem 1: A random sample obtained from a population with variance o²=400, and sample mean is computed to be = 70. Consider the null hypothesis Hu=80 and alternative hypothesis H₁: <80. Compute the critical value and state your decision rule for the following options regarding sample size: a) n=25 (b) n=16, (c) n=44 Also calculate 95% confidence interval for each of the case and make your decision rule.
