The frequency of electrical impulses (number per second) emitted from electric f

Question

The frequency of electrical impulses (number per second) emitted from electric fish was measured at varying temperatures degree C). (a) Calculate the Regression Coefficient. (b) Can impulse frequency be expressed as a function of temperature (Test beta = 0). (c) What proportion of the variation in impulse frequency can be explained the variation in temperature, (d) What is the predicted number of impulses emitted at a temperature of 26 degree C? (e) Give the specific equation that expresses number of impulses per second as a linear function of temperature.

Explanation / Answer

r = n * sigma(XY) - sigma(X). sigma(Y) / sqrt( [n.sigma(X2 ) - sigma(X)2].[n.sigma(Y2) - sigma(Y)2] )

r=0.9771
