Question

What does the model predict for 1900?

Answer 1

64.0% is the correct answer.

Explanation:

As per the given scatter plot of voter turnout every year:

X axis represents the year and

Y axis represents the percentage of people who voted.

The model was predicted as per the equation:

`y = -0.1271x + 307.53`

To find: Prediction for the year 1900.

Putting the value of
`x=1900`, the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.

`\Rightarrow y = -0.1271* (1900) + 307.53\\\Rightarrow y = -241.49 + 307.53\\\Rightarrow y = -64.04\%\\OR\\y \approx 64.0\%`

So, the model predicts
`y \approx 64.0\%` for the year 1900.
