A sample of size n 100 produced the sample mean of X 16 As

A sample of size n = 100 produced the sample mean of X - 16. Assuming the population standard deviation sigma = 3, compute a 95% confidence interval for the population mean mu. Suppose P is a probability function on a sample space S, A and B are events in S such that P(A) = 0.3, P(B) = 0.5, and P (A B) = 0.7. Find each of the following probabilities. Two balls are drawn, without replacement, from an urn with 6 red (R) blue (B) balls. Find the following probabilities. 2 red balls are drawn? 2 blue balls are drawn? At most one blue ball is drawn?
