    sample distribution
    The breaking strength of untreated fabric is normally distributed with mean 58 pounds and standard deviation 2.3 pounds. The same type of fabric after treatment has normally distributed with mean 30 pounds and standard deviation 1.6 pounds. A clothing manufacture testsan SRS of 5 specimens of each fabric.



    What is the probability that the mean breaking strength of the 5 treated specimens exceeds 50 pounds?
