11. An experiment is set up to study the weights of 45 frogs after they are given a hormone treatment. The population mean is 22.70 grams with a standard deviation of 2.96 grams. What is the standard error of the sample mean? Round your answer to the nearest hundredth.

The standard error of the sample mean is approximately (? ).

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
