Answer:
31 human cases.
Step-by-step explanation:
The least squares line equation for the number of reported dead birds (x), versus the number of human West Nile virus cases (y) is
y = -10.2638 + 0.0491x
If the number dead birds reported in a year is 844, then we have to find the numbers of human cases of West Nile virus.
To find the numbers we will plug in the value of x = 844 in the linear equation.
y = -10.2638 + 0.0491(844)
= -10.2638 + 41.4404
= 31.1766
≈ 31
Therefore, 31 human cases can be expected.
