Problem 1: A bakery uses a machine to dispense frosting over cupcakes. According to the manufactu the weight of the frosting that the machine places over a cupcake is a normally distributed random variable with mean 19.8g and variance 7.2g². Suppose that you take random samples of 30 cupcakes each and compute the mean weight of the frosting for the cupcakes in each sample. a) What is the mean and the standard deviation of the sampling distribution of X?
