A biologist studying Florida bass observed a quadratic relationship between the lengths and weights of fish in a large sample. The biologist took the base 10 logarithm for the values of both variables, and they noticed a linear relationship in the transformed data.
Here's the least-squares regression equation for the transformed data, where weight is in kilograms and length is in centimeters.
log(weight)=3.08log(length)−5.07
According to this model, what is the predicted weight of a Florida bass that is 70cm long?
You may round your answer to one decimal place.
