Consider the data set:

For this data we do not know how T depends on L. We hope that T is proportional to some power of L. Transform data by taking Logarithms and do linear regression. Upon computing the regression round to one decimal.
1.What is the slope?
2.What is R^{2}? Use two decimals
3.Predict the value of T when L = 5. Use one decimal
Here from above T is dependent variable and L is independent variable
So the regression line is
T= L*a+b
Hence our line is
T= 7.38744*L+67.09692
1. Slope of line is 7.38744
2. r = 0.3187
Hence the R^2 = 0.1015
3.predict the value of T when L= 5
Hence we have regression equation is
T= 7.38744*L+67.09692
T=7.38744*5+67.09692
T = 30.1597
Hence the predicted T is 30.1597
