Managing a new$-$product development process, managers often have to oversee a series of related activities directed to a desired goal or output. As a new$-$product development manager, you are responsible for two sequential steps of the product development process$-$namely, the development of product specifications followed by the design of the manufacturing process. Let $\backslash ($ X $\backslash )$ be the number of weeks required to complete the development of product specifications, and let $\backslash ($ Y $\backslash )$ be the number of weeks required to complete the design of the manufacturing process. Based on experience, you estimate the following probability distribution for the first step:

For the second step, your estimated distribution is

Calculate $\backslash (\backslash$mu$\_\{$X$\}\backslash )$ and $\backslash (\backslash$mu$\_\{$Y$\}\backslash ).$ Round to two decimal places when necessary.
