A scientist is testing certain sampling strategies to see which one is best. She's gathered data from an entire population and calculates a population mean & (mu) = 14 and a population standard deviation o (sigma) = 5. She draws five different samples from this population using five different strategies and gets the following sample means and standard deviations: Sample 1: 4 (x-bar) = 16.9, s = 6 Sample 2: X (x-bar) = 14.5, s = 4.7 Sample 3: x (x-bar) = 10.5, s = 3.3 Sample 4: x (x-bar) = 17, s = 4.9 Sample 5: x (x-bar) = 14.1, s = 8.4 Which sampling strategy does she conclude provides the best sample? A. Sample 1 O B. Sample 5 O C. Sample 2 O D. Sample 4 O E. Sample 3
