what is the answer to 9 and 10?

9. The mean and median of a probability distribution for a continuous random variable are 1 1.2 and 23.6, respectively. What is the shape of this distribution? The probability distribution is skewed to the right. The probability distribution is symmetric. The probability distribution is skewed to the left. There is no way to determine the shape of the probability distribution with this information. 10. A machine in a large factory is designed to mill a small lawnmower engine part out of a solid piece of aluminum. The distribution of times that it takes the machine to mill a part is approximately normally distributed with a mean of 39.2 seconds with a standard deviation of 14.2 seconds. Let X = the amount of time required to mill the engine part out of a randomly selected piece of aluminum. Using the 68-95-99.7 rule, calculate P(X" > 10.8 ) . 0.025 d s 0.0015 0.84 None of these is correct
