The percent error in the meteorologist's forecast for Monday is 5.26316 %
Solution:
Given that Monday's high temperature would be 76°F
On Monday, the temperature reached 80°F
To find: percent error in the meteorologist's forecast for Monday
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
The percent error is given as:
[tex]\text {percent error }=\frac{\text {observed - standard}}{\text { standard value}} \times 100[/tex]
Here standard value = 76 and observed value on monday = 80
[tex]\text { percent error }=\frac{80-76}{76} \times 100[/tex]
[tex]\text { percent error }=\frac{4}{76} \times 100=5.26316 \%[/tex]
Thus percent error in the meteorologist's forecast for Monday is 5.26316 %
