A biologist was interested in the relationship between the ve- locity at which a beluga whale swims and the tail-beat fre- quency of the whale. A sample of 19 whales was studied and measurements were made on swimming velocity, measured in units of body lengths of the whale per second and tail-beat frequency, measured in units of hertz (number of tail beat per 1.0 0.3 SWImmIng Speed {Body Length per Second} second) The following regression output is for predicting the :3 swimming speed of a beluga Whale from it's tail-b eat frequency. Part of the output is blurred. 't o Coefficients: Estimate Std.
