The gateway arch in st. louis, missouri, weighs about 20,000 tons. write an amount that could be the exact number of tons the arch weighs

We can choose any numbers that would round up or round down to 20000

Any numbers between 19500 and 19999 would round up to 20000
Any numbers between 20001 and 24999 would round down to 2000

For example, the number 19659 would round up to 20000, or the number 21564 would round down to 20000.

Answer : There will be two outliers occurring where fibrinogen levels encroach and exceed 4. The two points, where ESR is less than 20 occur at high fibrinogen levels in the blood, the first is the closest point to 4, and the second is beyond a fibrinogen level of 5.

We can assume and deduce the two outliers not only because of the high levels of fibrinogen, but because the globulin levels do not increase as deduced by the other points in the plot.
