Situation Given Answer Standard error formula 1. Consider a population consisting of N= 1, 2, 3, 4, 5, 8, 9, and 11. Samples of size 3 are drawn from this population. n = 2. Given the population mean of 12, 1 = and a sample standard deviation of 3 in a sample size of 125 S = 3. A population composed of 11 items whose measurements are 12, 7. N = 9,11,8, 20, 23, 18, 13, 22, and 10. n = Samples of 5 items are drawn at random without replacement. 4. The owner of the drugstore chain has 100 drugstores that sell Flexcoslow, a surgical mask that W = prevents a person from catching liquid droplets of viruses. His operation manager said that the U= average drugstores in his chain sell 12 boxes of the Flexgoslow a day with a standard deviation of 2 boxes. To find out if this is true, the owner randomly S= selected 10 stores and found that the mean is 15 boxes with a standard deviation of 1 box
