Make sure to do the calculations by hand, not in Python. Fit regression models to these data:

$($a$)$ Use an exponential model

$($a$1-15$ pts$)$ Manually $($feel free to use Excel$)$ calculate all needed numbers $1$ to obtain $k($slope$),$

$b($intercept$),{}_1$ and ${}_1,r^2$ and $S_e.$ Also write$/$type the actual exponential equation.

$.$

$($b$)$ Use a power model

$($b$1-15$ pts$)$ Manually $($feel free to use Excel$)$ calculate all needed numbers like to obtain $k$

$($slope$),b($intercept$),{}_2$ and ${}_2,r^2$ and $S_e.$ Also write$/$type the actual power equation.
