Find the sample size necessary to construct a z-confidence interval at the given level of confidence, and within a given distance of the true population mean: 0 CL : 88%, c : 4, within 1 of the true population mean Step 1: a 2 Step 2: oc/Z :I Step 3: 2% 2 Step 4: n : 0 CL : 92%, o : L within 4 of the true population mean Step 1: Step 2: Step 3: Step 4: 0 CL : 99%, c : it within 2 ofthe true population mean Step 1: Step 2: Step 3: Step 4
