Use the lm() function to fit the linear model which describes quality_of_life as a function of unemployment_p.

What quality of life would you predict if you knew the unemployment percentage in a neighbourhood was #6.2#? And if it was #19.7\%# or #21.8\%#? Give your answers in one decimal.

w i s h_t o_m o v e = 77.995 - 7.083 \cdot q u a l i t y_o f_l i f e

The predicted quality of life in a neighbourhood with an unemployment percentage of #6.2\%# is

The predicted quality of life in a neighbourhood with an unemployment percentage of #19.7\%# is

The predicted quality of life in a neighbourhood with an unemployment percentage of #21.8\%# is
