Q$6$: Consider the data in the following table:

$1-$ Estimate the parameters B$\text{'}$s in the model: $y=B_0+B_1{x}_1+B_2{x}_2.$

$2-$ Construct ANOVA table and test to determine if the overall regression is statistically

significant $(=0\mathrm{.}05).$

Note: $([6,39,13],[39,271,91],[13,91,35]{)}^{-1}=([2\mathrm{.}595,-0\mathrm{.}392,0\mathrm{.}056],[-0\mathrm{.}392,0\mathrm{.}088,-0\mathrm{.}084],[0\mathrm{.}056,-0\mathrm{.}084,0\mathrm{.}226])$
