Give me the Python code please.

$($a$)$ Write your own function myconf which takes as arguments a fitted model fit $($from simple linear

regression$),$ an independent variable $x$ and a specified confidence level $.$ The function should output

the value of the mean response at $x$ and the confidence interval based on the $$ level specified. For this

part DO NOT use built$-$in prediction functions such as fit.predict or conf$\_$int.

$($b$)$ Using the dataset from the file cars.csv fit dist vs speed $($as the independent variable$)$ using a

linear model and generate the outputs from the myconf function using the fitted model, $x=14,18$ and

$=0\mathrm{.}95($for both values of $x).$
