(a) Use the data in the table to find the least-squares regression line. Round the slope to two decimal places and the y-intercept to
the nearest whole unit.
(b) Use a graphing utility to graph the regression line and the observed data, then choose the correct graph from the options
below.
(©) Use the model in part (a) to approximate the wind speed of a hurricane with barometric pressure of 930 mb. Round to the
nearest mph.

(a) Use the data in the table to find the least-squares regression line. Round the slope to two decimal places and the y-
intercept to the nearest whole unit.
The equation for the least-squares regression line is y=
