e Linear Regression
The regression formula for linear regression is: y = A+ Br.
¢ Example: Atmospheric Pressure vs. Temperature
Perform linear regressi ter-

mine the regression formula terms
|_ 10°C _{ 1003 hPa and correlation coefficient for the
data nearby. Next, use the regres-
sion formula to estimate atmos-
pheric pressure at 18°C and tem-
perature at 1000 hPa.
