the table below shows lemon imports (in metric tone) and cash fatality rate.

lemon imports[ 230 265 358 480 530]

crash fatality rate[ 15.9 15.7 15.4 15.3 14.9 ]

a) are lemon imports and crash fatality rate correlated? test at 5% significance.

b)Using a regression line, what do you predict the crash fatality rate when 500 metric tons of lemons are imported?
