Joel reads on the package of cereal that the net weight of the box is 64 oz. He calls the company to find out how they guarantee this and they tell him that the filling machine is set to fill each box with 64.8 oz with a standard deviation of 0.6 oz. He graphed
the normal distribution of the package weights. Using his graph, what percentage of boxes does the shading represent? Is this
appropriate?
A)
The shading represents 90% of the boxes. Yes, this is appropriate as 90% of
the boxes are at least the stated weight.
B)
The shading represents 9% of the boxes. Yes, this is appropriate as less
than 10% of the boxes are under the stated weight.
C)
The shading represents 9% of the boxes. No, this is not appropriate as
more than 10% of the boxes are under the stated weight.
D)
The shading represents 90% of the boxes. No, this is not appropriate as
less than 10% of the boxes are under the stated weight.
