Calculate the Norton Resistance and Current and the Thevenin Voltage of the following circuit
I answered your last question here.

Once again, you have the right answer and your "solution" answer is wrong.

You have done the correct method; found the open-circuit terminal voltage, which is the Thevenin voltage. You have then found the Thevenin resistance - also correct. You have then used the transform \$ I_n = V_{th}/R_{th}\$ to find the Norton current, correct again.

Good job - wherever you keep getting your solution answers from, stop using it!!!
