The equation y = 450x represents the relationship between x, the time that a plane
flies in hours, and y, the distance the plane flies in miles for Plane A. The table
represents the relationship for Plane B. Find the slope of the graph for each plane and
the plane's rate of speed. Determine which plane is flying at a faster rate of speed.

The slope of the graph of Plane A is
and its rate of speed is
mi/h.
The slope of the graph of Plane B is
and its rate of speed is
mi/h.
Plane (select)
is flying faster.

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 25, a standard deviation of 2.5, and margin of error of 5%
