Hi. Er der nogle der kan hjælp med opgaven:
"The length of a steel rod should be 5m, and a deviation of 1cm longer or shorter is tolerated, otherwise the steel rod is scrapped. Suppose a steel rod conforms to the specifications roughly 68% of the time, which of the following is the best estimation for the standard deviation (in meters) if the process is normally distributed with a mean of 5m?"
