Q4: The strength of the cubic concrete of the first line production is 110 N/mm and standard deviation =12 N/mm' and for the second line production is 95 N/mm' and standard deviation =10 N/mm. If two samples are taken from each line, n=100X for each and the strength are tested, find the probability that the strength of 1" line greater than the 2nd line by: a- 17 N/mm or more b- 35 N/mm or more X=0.74
