The following data show the relationship between the viscosity of SAE 70 oil and temperature. After taking the log of the data, use linear regression to find the equation of the line that best fits the data and the r2 value.
Temperature, °c | 26.67 | 93.33 | 148.89 | 315.56 |
visscosity,µ,N.S/m2 | 1.35 | 0.085 | 0.012 | 0.00075 |
