Here is a probability distribution for a random variable $X$ : Let $Y=4X?2$. Use the rules for means to find the mean of the distribution of $Y$. Give your answer to one decimal place. ${?}_Y=$ Use the rules for variances to find the standard deviation of the distribution of $Y$. Give your answer to two decimal places. ${?}_Y=$
