Answer:
The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato chip bag assembly line.
Step-by-step explanation:
z- score for pop corn
average weight for a pop corn bag=3.05
Standard deviation for a pop corn bag=0.04
z=x-mean/standard deviation
z=3.03-3.05/0.04
z=-0.5
z- score for potato chips
average weight for a potato chips bag=5.01
Standard deviation for a potato chips bag=0.05
z=x-mean/standard deviation
z=5.07-5.01/0.05
z=1.2
As z-score for pop corn bag -0.5 is closer to standard mean i.e. 0 than the z-score for potato chips bag, so,
The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato chip bag assembly line.
