Assume the random variable X follows a Binomial Distribution with number of trial n and probability of success p. The probability mass function of the distribution is give as follows: P(X = x) = Qp*q"-, x = 0,1,2,..,n. Il y = 1-p Then show that E(X) = np and V(X) = npq. ​

Select the correct answer from each drop-down menu. james needs to clock a minimum of 9 hours per day at work. the data set records his daily work hours, which vary between 9 hours and 12 hours, for a certain number of days. {9, 9.5, 10, 10.5, 10.5, 11, 11, 11.5, 11.5, 11.5, 12, 12}. the median number of hours james worked is . the skew of the distribution is
