How do i plot probability density curve with actual values as vertical line (as the picture attached)? And how to interpret that according to the distribution? Thank you.

If the distribution function is provided, along with the necessary parameters (none of which are prrovided here), this is straightforward —
x = linspace(1500, 2100);
mu = 1800;
sigma = 75;
npdf = normpdf(x, mu, sigma); % Use Normal Distribution To Demonstrate
npdf = 1×100
0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0001 0.0001 0.0001 0.0001 0.0001 0.0002 0.0002 0.0003 0.0003 0.0004 0.0005 0.0005 0.0006 0.0007 0.0009 0.0010 0.0012 0.0013
figure
patch([x flip(x)], [zeros(size(npdf)) flip(npdf) ], 'b', 'FaceAlpha',0.25)
hold on
plot([1 1]*mu, [0 normpdf(mu, mu, sigma)], '-r', 'LineWidth',2)
hold off
Experiment with the intended distribution function and parameters.
