Observe that for a random variable Y that takes on values 0 and 1, the expected value of Y is defined as follows: Now, suppose that X is a Bernoulli random variable with success probability Pr (X = 1) = p. Use the information above to answer the following questions. Show that . = ( ) + ( p) = (Use the tool palette on the right to insert superscripts. Enter you answer in the same format as above.) Suppose that p = . Compute the mean of X. = (Round your response to two decimal places) Compute the variance of X. = (Round your response to three decimal places) Compute the skewness of X using the following formula: Skewness of X = (Round your response to three decimal places) Compute the kurtosis of X using the following formula: Kurtosis of X = (Round your response to three decimal places) Enter your answer in each of the answer boxes.
