Answer:
Maximum altitude: 52.53 km
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>Consider the following data set which relates the hemoglobin levels h (kg/dL) of workers and the altitude a (km) above the sea level that the workers exposed over years:
</em>
<em>
</em>
<em>a 0.32 0.64 1.28 1.60
</em>
<em>h 1.15 1.10 1.05 0.95
</em>
<em>
</em>
<em>In the regression model , the constant c2 is found as c2 = 0.1315. Assuming the hemoglobin concentration for the residents at the highest permanently tolerable altitude of the atmosphere is the 1/1000th of the hemoglobin concentration for the residents at sea level, compute the highest permanently tolerable altitude in kilometers.</em>

We have to calculate the maximum altitude that the residents/workers can tolerate.
This altitude is at which the hemoglobin conventration is 0.001 of the concentration at sea level.
We can calculate this as:

The highest permanently tolerable altitude is 52.53 km.
