Quantitative sleepuse the quantitative response variable SleepHrsNight and do the exercise$\mathrm{.}1.$ Build a classifier for SleepHrsNight$\mathrm{.}2.$ Report its effectiveness on the NHANES training data$\mathrm{.}3.$ Make an appropriate visualization of the model$\mathrm{.}4.$ Interpret the results. What have you learned about peoples sleeping habits? and Build and interpret the following models: Null model Multiple regression Regression tree Random forestThis is how you can import the data set NHANES.In Python:pip install nhanesfrom nhanes.load import load$\_$NHANES$\_$data, load$\_$NHANES$\_$metadata data$\_$df $=$ load$\_$NHANES$\_$data$($year$=\text{'}2017-2018\text{'})$metadata$\_$df $=$ load$\_$NHANES$\_$metadata$($year$=\text{'}2017-2018\text{'})$
