Let X be a random variable that represents the amount of time a randomly selected person spent on social media yesterday. Suppose it is known that X is skewed to the right with the population mean = 3 and standard deviation = 3 (in hours). Let X be the sample mean from a random sample of 9 people.

a) What is the mean of x (X ) and standard deviation of X (X )?

b) Is X normally distributed? Explain
