Question

For exercise 19 and 20, use the table that shows the percent of people age 25 and over with a high school diploma over the last few decades.

20. Do you think your prediction is accurate? Explain.

Step-by-Step Solution

Verified

Answer

No, the predicted percent is not accurate because it is certainly too high. Since the percent cannot exceed 100%, it cannot continue to increase indefinitely at linear rate.

1Step-1 – The prediction equation.

Consider Elevation as x coordinate and Average Precip. as y coordinates

The equation for the prediction is $y = - 0.04 x + 34.52$

2Step-2 – The prediction percent in 2010.

The model predicts that $96.1 %$ of people will have a high school diploma in 2010.

3Step-3 – Determine the prediction is accurate or not.

No, the predicted percent is not accurate because it is certainly too high. Since the percent cannot exceed 100%, it cannot continue to increase indefinitely at linear rate.
