b$.$ Create the following dummy variables: $Qtr1=1$ if quarter

$1,0$ otherwise; $Qtr2=1$ if quarter $2,0$ otherwise; $Qtr3=1$ if

quarter $3,0$ otherwise. Create a variable $t$ such that $t=1$ for

quarter $1$ of year $1,t=2$ for quarter $2$ of year $1,$dots,$t=12$ for

quarter $4$ of year $3.$ Use these dummy variables and $t$ to

develop an estimated regression equation to account for

seasonal effects and any linear trend in the data. What is the

forecast for quarter $1$ of next year?c$.$ What is the forecast for quarter $2$ of next year?
