a$.$ Compute the labor productivity and the multifactor productivity for each unit. Use an eight$-$hour day for multifactor productivity. $($Round your "Labor Productivity" answers to $1$ decimal place and "Multifactor Productivity" answers to $3$ decimal places.$)$

b$.$ Suppose a new, more standardized procedure is to be introduced that will enable each employee to process one additional customer per day. Compute the expected labor and multifactor productivity rates for each unit. $($Round your "Labor Productivity" answers to $1$ decimal place and "Multifactor Productivity" answers to $3$ decimal places.$)$
