12. The Department of Health has the following data of the number of infected persons of Covid-19 in five high-risk areas in the country, 51, 89, 129, 215, and 297. Suppose samples of size 2 high-risk areas are drawn from this population, what example of the sampling distribution of the sample mean for normal population portrays the situation? A. variance is known B. variance is unknown C. standard deviation is small D. standard deviation is large O 13. Givenu = 88, X = 90 s = 2, and n = 15. This is an example of the sampling distribution of the sample mean for a normal population when the population variance is A. unknown B. known C. large D. small
