A chef makes the pizza in two steps. The first step is to prepare the dough and kneading it. The amount of time it takes to finish the first step is represented by a mean time of 10 minutes and a standard deviation of 3 minutes. This is followed by adding the toppings with cheese and baking it in the oven. This second step has a mean of 7 minutes seconds and a standard deviation of 2 minutes. If these two steps run in sequence, what is the mean time required for the entire process?
