The table shows the yield $($in bushels per acre$)$ and the total production $($in millions of bushels$)$ for corn in a country for selected years since $1950.$ Let $x$ represent years since $1900.$ Find a logarithmic regression model $)=(a+blnx$ for the yield. Estimate the yield in $2021.$

$\backslash$table$[[$Year$,$X$,$Yield$],[1950,50,39],[1960,60,60],[1970,70,85],[1980,80,92],[1990,90,114],[2000,100,146],[2010,110,150]]$

The regression model is $y=+(,)lnx.$

$($Round to one decimal place as needed.$)$

The estimated yield in $2021$ is bushels$/$acre$.$

$($Round to the nearest integer.$)$
