Use the dataframe created in the next code cell and complete tasks $1-6$ to generate the following figure:

$1.$ Create a scatterplot, where the x$-$axis corresponds to the default index of the dataframe, and the y$-$axis represents the values from the column Y$.$

$2.$ Calculate the mean of Y and show it as a solid horizontal line on the graph.

$3.$ Calculate the standard deviation of Y and draw two dashed lines, each representing one standard deviation away from the mean.

$4.$ Set x$-$axis and y$-$axis limits as $[-1,11]$ and $[-20,30]$ respectively.

$5.$ Enhance plot clarity by removing ticks on the x$-$axis.

$6.$ Set the legend in the bottom$-$right corner of the graph.
