Use the first one as your reference. Standard Error of the Mean Formula to Is Population Variance (Known or Unknown) Problem/Situation Given be Used 1. Consider a population consisting of 1, 2, 3, 4, 5, 8, 9, and 11. Samples of size 3 are drawn from this population. N=8; n=56; p=5.375 Known 2. The owner of the drugstore chain has 100 drugstores that sell Flexcoslow, a surgical mask that prevents a person from catching liquid droplets of viruses. His operation manager said that the average drugstores in his chain sell 12 boxes of the Flexcoslow a day with a standard deviation of 2 boxes. To find out if this is true, the owner randomly selected 10 stores and found that the mean is 15 boxes with a standard deviation of 1 box. N = He = 3. The mean height of the students at Maligaya Elementary School is 137.16 cm. To find out if the statement is true, a sample of 15 students is taken from the H = S3 = population. The mean of the sample is 139.1 cm with a standard deviation of 2.23 cm. 4. Consider a population consisting of 15, 2, 12, 4, 5, 8, 6, 9 and 17. Samples of size 5 are drawn from this population. N =
