naive approach. The linear trend equation is Ft $=124+2\mathrm{.}1$t$,$ and it was developed using data from periods $1$ through $10.$ Based on data for periods $11$ through $20$ as shown in the table, which of these two methods has the greater accuracy if MAD and MSE are used? $($Round your intermediate calculations and final answers to $2$ decimal places.$)$
