The required greatest percent error among the predictions is 1.773% approx 1.8%
Given that,
The dot plot shows predictions for the winning time in the 200-meter sprint. The winner finished the race in 22.5 seconds.
We have to determine,
What is the greatest percent error among the predictions.
According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds.
Divide this over the true time value to get prediction,
[tex]= \frac{0.4}{22.5} = 0.0177 = 1.77%[/tex]
Which is approximate.
Move the decimal point to the right 2 spots to get to 1.773% approx 1.8%
Hence, The required greatest percent error among the predictions is 1.773% approx 1.8%
