Help me with the statistical problem, please.
Each minute a ma- chine produces a rope of length with mean of 4 feet and standard deviation of 5 inches. (Pay attention to units). Note that you are not told the distribution function. Make the assumption that the lengths of different ropes are independent and identically dis- tributed.

Give the answer in terms of the normal distri- bution function and a numerical answer
