The events X and Yare mutually exclusive. Suppose P(X) 0.07 and P(Y) 0.05 (1) What is the probability of either X or Y occurring? (Round your answer to 2 decimal places.) Probability (2) What is the probability that neither X nor Y will happen? (Round your answer to 2 decimal places.) Probability
Consider the probability distribution shown below. x 0 1 2 P(x) 0.05 0.80 0.15 Compute the expected value of the distribution. Compute the standard deviation of the distribution. (Round your answer to four decimal places.)
Consider the probability distribution shown below. x 0 1 2 P(x) 0.25 0.70 0.05 Compute the expected value of the distribution. Compute the standard deviation of the distribution. (Round your answer to four decimal places.)
We usually compare the calculated p value with 0.05. What does 0.05 mean? Why can we reject the null hypothesis if the calculated p values is smaller than 0.05?
