Document Summary

If x is a discrete random variable taking on values. Least squares regression line: : where , and , residual . with respective probabilities , then the mean . If y = a + b x, then and. P(a or b) = p(a) + p(b) p(a and b) If p(b) > 0 then p(a | b) = p(a and b)/p(b) If a and b are independent events, p(a and b) = If a and b are disjoint events, p(a and b) = 0. General multiplication rule: p(a and b) = p(a) * Let x denote the sample count of successes out of a srs of size n from a population with population proportion of successes. X is approximately normal ( ) . Formulae: a srs of size n from a population with population simple random sample of size n. suppose the population standard deviation is known. Let denote the sample proportion out of proportion .
