Extracted text: Problem 3: A factory mamufactures a specific copper part. It is found at a certain temperature the resistance in m? of this part is normally distributed with mean of 23.8 and standard deviation of 1.23. Among 5000 units of such parts, how many units are likely to have a resistance (a) less than 23? (b) greater than 24? (c) between 24.2 and 24.5?
