(a)Draw a scatter diagram treating atmospheric pressure as theexplanatory variable.
(b)determine the linear correlation coefficient between atmosphericpressure and wind speed.
(c)Does a linear relation exist between atmospheric pressure and windspeed?
D. Make sure that your scatter diagram includes a title and theaxes are labeled.
