The owner of the drugstore N: chain has 100 drugstores that sell surgical mask that prevents a = Flexcoslow, 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 boxes. To find out ir this is true, the owner randomly selected found that the mean is 15 boxes deviation of 1 box. deviation of 2 10 stores and with a. standard The mean height of the students Elementary 137.16 cm. To find out if the statement is true, a sample of 15 students is taken from the population. The mean of the sample is 139.1 cm with a standard deviation of 2.23 Maligaya 8 School at %3D is

Determine whether the following stateieneo have a known or unknown population variance and provide a brief explanation to support your answer. Also, identify the formula to be used for the standard error of the mean by writing 0g, when the population variance is known and S when e population variance is unknown

 

Answer 4 and 5 only

2. Given the population mean of 12, and standard deviation of 3 in a sample size of 125 a sample 3. A population composed of N= items 11 whose measurements are 12, 7, 9,11,8, 20, 23, 18, 13, 22, and 10. Samples of 5 items drawn without replacement. are at random 4. The owner of the drugstore N = n=_ chain has 100 drugstores that sell Flexcoslow, a surgical mask that prevents 0 = from catching person 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 boxes. To find out ir this is true, the owner randomly selected found that the mean is 15 boxes deviation of 1 box. %3= deviation of 2 10 stores and with standard S. The mean height of the students Elementary 137.16 cm. To find out if the statement is true, a sample of 15 students is taken from the population.
