What is your actual question? You have calculated what you were supposed to. I guessing that the result wasn't what you expected. I'm not going to give you a ready made answer to a question you didn't ask. In an R console do ?rweibull and read carefully about the shape and scale arguments in the Details section. That should help you to understand your results.
