Situation: A population of public school teachers with cars in 5 schools in San Pablo City are (x) 8, 4, 5, 10, and 12. Suppose that two schools were selected as samples, determine the mean and variance of the sampling distribution of the sample mean. Sample Mean Probability (S Mean - P Mean) (S. Mean - P. Mean) P-X(X - P(X) (X-P) (x - 1) Total​
